In other words. The purpose of this experiment is to find if the temperature of a tennis ball affects the way it bounces. Your email address will not be published. Tension Loss. Tension loss is defined as just that part that occurs after stretching. This is not the expected result. The independent variable is temperature. These muscles are used to accelerate the whole arm while also stabilising the shoulder. The thermocouple recorded the temperature. Ball History. Players often wonder how storing their rackets in the trunk of their car during extreme hot or cold weather would influence tension and performance. Try comparing a baseball to a golf ball or a tennis ball. When a tennis balls temperature changes, the gas core goes through a reaction. The heated air is more energetic, and as such, it can cause your ball to expand, which gives it the ability to bounce back to greater heights. It is the net result of the effects of elongation, tension, strain rate and temperature. Will the Temperature of a Tennis Ball Affect the way it bounces? For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder. A string was inserted inside clear perspex tube with two open ends and through a small hole in a rubber stopper at each end of the tube. Fourteen strings were tested: 1 gut, 1 kevlar, 7 nylon, 5 polyester. Hockey Stick Contribution to Puck Speed in Slap Shots, Introduction to the Physics of Hockey Sticks. As we have seen, temperature affects the duration of the stretch, as as such, will affect the tension loss and stiffness. Borlings, D. (2011). The question also required me to determ wheter or not I could use the same weight as I normally do while using the stability ball? The greatest effect observed in this experiment was that exposing a string to high temperatures after post-tensioning stabilization/relaxation has occurred (as in leaving the racquet in the car during hot weather) produces the greatest decrease in tension. I should also research to determine who should not use a stability ball. The courts are designed so that the ball can bounce off any surface and still be in play, yet it is in a confined area so you don't have to run to cover too much territory. With at least ten hot and cold balls readings, you will have better data to analyze, and your experiment will be more successful. Figure 11 Tension loss by temperature in setup #2. Tennis Reviewer is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com. The temperature regression was carried out last. As a result, a cold ball has a much lower bounce. The distance between clamps was 35 cm. The string ends extended past the end of the tube and were clamped. University of Virginia Physics Department, n.d. The stiffness tests closely approximated the expected result that stiffness would have an inverse relationship to increase in temperature. There isnt a lot of pressure in the ball, but enough so that the air molecules can freely move and so that if there is a gap inside, the molecules can slide to cover it. After doing this activity, I observed that as temperature decreases so does the pressure. Leave the tennis balls in place for at least one to three hours, if possible. I chose to perform the ab crunch for my abs. The bladders are usually made of rubber or rubber like things. The ball will not bounce much in the winter, which means that the players will not be as active on the field as they are during the summer season. Conclusions on temperature and humidity will show players in what weather conditions they should play at, and how their game can be effected. Tension was recorded throughout the process. In general, players can compensate by adjusting playing style as well as making technical tweaks to their rackets and stringing configurations. If the uniform temperature of a tennis ball is decreased, the balls bounce will be lower. Figure 12 Tension vs time for a string tensioned to 28 kg for several different time intervals prior to clamping. The pressure of the gas inside the ball ultimately determines how high the tennis ball will bounce. Pen. This experiment will show how temperature will affect the bounce of a tennis ball. Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius.

Temperature Cubic ANOVA. Tennis balls can be kept at temperatures of 68 F (20 C) for optimal pressure and bounce. Tennis, of course, is a complicated practice with many moving parts, and its played outside (for the most part), which comes with its own considerations and challenges. Table 9: Ball 1 vs. Setup #2 Stiffness, Elongation, and Tension vs Temperature. Required fields are marked *. Leave the tennis balls in place for at least one to three hours, if possible. Using tongs, push the squash ball under the water for about 2 minutes. Tests with this apparatus were conducted at 20 C and 40 C. 20 C was room temperature with air conditioning. Rather, it is something that naturally happens. These acquired values show that the line is a good predictor of future points and where they will fall. Does Air Pressure Affect the Bounce of a Basketball? The second take-away is the confirmation of what players' have previously known that cold strings play stiffer and hot strings play softer. So, for the most part, adapting to weather or other environmental conditions can usually be done relatively quickly. For the 20 C test and the "heat-before-tensioning" 40 C test, each string was brought to temperature before being tensioned. Equilibrium occurs when all molecular bond attractions are greater than the tension trying to tear them apart. America seemed very separated from the game until a sweep of popularity in California in 1989. Stiffness decreases with an increase in temperature and increases with a decrease in temperature. Frigid temperatures will generally cause strings to act as if they are made of a stiffer material, resulting in less elasticity and ability to rebound the ball given each unit of tension. Setup #1 Tension vs timing of heat application. Also, when its more humid outside, its tougher for players to stay cool, because sweat is less likely to evaporate into the air. You can get an idea of just how much by looking at the percentage difference in stiffness resulting from the temperature exposures. (Sheehan, 2011)Its just like a trampoline: When one jumps on a trampoline, the material one the trampoline expands and stretches, and when it does, the trampoline is forced to come back up to its original state, causing one to bounce on the trampoline. When the temperature increases, the gas molecules inside the tennis ball expand. Analysis The heated tennis balls bounced the highest because as the temperature rose, the molecules expanded and exerted more pressure when the ball bounced The experiment illustrated the perfect gas law, because it showed that when the temperature rose, so did the pressure The data for each set of tennis balls had a range of 15 . Time was analyzed next in Table 3, 4. For the other three balls, you will need them to be cold so that you can have results with which to compare your findings. Gather 15 to 20 tennis balls and a measuring tape. Continue the same procedure until all balls have been tested. Figure 1 Experimental setup for measuring tension loss vs time for strings with different temperature exposure histories. This means that the pressure is optimal for performance on the field. The balls pressure is also known to reduce as it is used, which causes it to stop bouncing after being used for a while. Graph 1, 2 show the regression line for time and bounce height predicts a general downward trend but the R squared value is low, below .17 in both cases. Most players focus on tension, but that is only useful in as much as it predicts stiffness, which is often the case for comparing an individual string at different tensions but not for comparing different strings to each other. 5.Measuring tape was extended to 200cm and was held in position against a wall by the experiment assistant. (Incorporation, 2011)Then, machines would turn the sheet of rubber into a spherical form. The normal probability plot of residual graphs 21, 22 both show generally a straight line, when the extremities are neglected. Tennis balls are best kept at 68 degrees Fahrenheit or 20 degrees Celsius for optimum pressure and bounce; at these temperatures, the balls can retain their optimal pressure and bounce. A good source of heat that can heat things evenly. Using balls that are all new means that your experiment will be more consistent, and as such, you will be able to get the best kind of results. The difference in stiffness between temperatures for each string was greater for the nylon strings. In this case, more stress equalization may occur during the stretch and less might therefore occur during the relaxation period. The most striking result is how much tension is lost during the 40 C post-tensioning-heating scenario compared to room temperature. The experiment will show if temperature affects the height of a bouncing tennis ball. (Borlings, 2011)They did not bounce very well, however. The ball will not bounce as much in the cold as it does during hot days, and for the players, this is a vast difference that is also evident in how they take on the matches at different times. Experiment. Figure 12 Closeup of tension loss vs temperature for each nylon and polyester string. Here is the data collected from the first bounce of each temperature. Gather 15 to 20 tennis balls and a measuring tape. When a tennis ball hits the ground, the force presses against the ball, pushing the bottom surface of the ball in to the core and compressing the gas inside of it. Dependant variables:How High the Ball Bounces. A warmer ball will bounce higher than a cold one. Signature: ___________________________________________________. (Sheehan, 2011)On impact, the gas will be caused to move toward the ground. This reordering occurs during both the stretching and post-stretching phases. By using a 1 meter ruler to measure the bounce height in centimeters. They found that tennis rackets perform noticeably differently at different temperatures, as well as be affected by the conditions during which stringing itself takes place. After ten games, tennis balls are known to have a rebound ratio of less than 53%. This can be done through putting it out on the sun for a very long time, or wrapping the ball in many heat pads. As the molecules expand, their energy increases as they bounce around more erratically. It is interesting to heat a tennis ball to see how better it can bounce when it hits the ground. The bladder inside the ball is what holds the air. Copyright 2023 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Why don't you do an experiment. Record the temperature on the thermometer. Stiffness and elongation are proportional to temperature, though the effect is not great. (Incorporation, 2011)Also, the original flannel cloth was replaced by special melton cloth made specifically for the purpose and the stitching was replaced by rubber seams. The more extended height from which you drop off the balls is also helpful and means that you can make more accurate observations. 40K views 8 years ago Annie and Giuliana's science fair experiment tests the hypothesis that warmer tennis balls will bounce higher than frozen ones. Later, the data would be compared by calculating the percentage of the bounce height over the initial height. Application of the Concept to the Real World, 10 Tips To Win Doubles Tennis With A Weak Partner. From that data, the lengthwise stiffness of each string was calculated. This type of heating has a permanent effect. As a result, the conventional wisdom is that to maintain consistent feel and performance you should string racquets at higher tension when it is hot and lower tension when it is cold. A tennis ball is designed as a hollow rubber core with pressurized air. They were first used by the French monks in the game known asJeu de Paume. (Borlings, 2011)These balls were often packed with sawdust wrapped in leather. The physiology of a tennis ball contains a hollow core made out of a rubber-like material. (Borlings, 2011) From the 1920s, the process of making a tennis ball was based on the clover-leaf principlewhere a sheet of rubber was shaped into a three-leaf clover. Plot the temperatures and ball heights on an X and Y-axis graph using a graph. It is the interplay between stretch rate, stretch amount, stretch duration, temperature, and stress relaxation that effects the amount of tension loss that occurs only in the relaxation period (the period that was measured to get "tension loss"). Does it matter when the string is exposed to a temperature extreme before, during, or after tensioning? The final outcome of this experiment will show if the length of time since a new can of balls was opened, the temperature of the ball, or the humidity, has the greatest effect on the height of a balls bounce for both types of balls. The value of the test statistic was found to be 0.40997 with an alpha level of 0.05 the H0 hypotheses would not be rejected. Sometimes, new balls might give you different results than older balls which means that your experiment will require a new source of data to determine whether you are getting accurate results. One may also use a heat dish to do this. Copyright 2023 Elite Tennis Guide | All Rights Reserved. Temperature were Plotted in 15, 16 both again show similar patterns indicating a upward trend in the data and poor randomness, both would be considered poor indications of a good fit. The temperature of the golf ball and the air temperature on the day you're playing directly affect how your ball will perform during a round. What is happening? This showed that the non-championship ball was more consistent than the championship ball in the test. Results for Setup #2 ‐ Elongation, Tension and Stiffness vs Temperature. Heating the string, whether before or during tensioning increases the mobility of the molecule chains. Background Research The final outcome of this experiment will show if the length of time since a new can of balls was opened, the temperature of the ball, or the humidity, has the greatest effect on the height of a balls bounce for both types of balls. Heating pad Jeu de Paume was played without even bouncing the balland was just played against a wall. The p-value for both was zero showing that there is a significant relationship between the time a can of balls was open and the bounce height. During fast volley bouts your muscles often react. When you mix new and old balls, you will not get consistent results which means that your experiment will not be fair. Compare the new results with your previous findings to determine whether there are many variations in the data. On the other hand, a temperature decrease causes the gas molecules to contract and move around more sluggishly. The residual vs. Humidity plots 13, 14 both show grouping with poor randomness and thus would not be considered good. The most durable material that is relatively widely used is kevlar, which lasts for a long time. A good example of this would be, when designing buildings to survive in areas where earthquakes happen frequently. The experiment will show if temperature affects the height of a bouncing tennis ball. A residual analysis was next completed for the liner regression. Perform steps 10-13 three times. Tension stabilization continues forever, but at a continually decreasing pace. Figure 9 Elongation by temperature in setup #2. The cubic fit is shown by R squared values of .396 and .331 and, the regression is able to predict between two and three times as many of the points as the linear regression. Players will be able to use the conclusions in many ways. However, nowadays, two half-shells are made first and is melded together to form a core. Bocce ball is a great way to demonstrate the complex wonders of Newtons three laws in a simple and understandable way. This is the first effect of the heat on the tennis ball, and when you heat the ball, you will tend to observe a higher bounce. Knowing this can help your scores. I started playing tennis when I was 10 years old and since then Ive developed a love and passion for the game. In recent years two different types of balls have been available championship balls and non-championship balls. You will also have a more comfortable time working out the heights to which the balls can rebound, and as such, your experiment will go on more easily. Method 1) 2 rubber balls were left sitting at room temperature, and 1.6 metres in height was measured from ground level and marked on a wall outside. The result differed from expectation in that, except for 4 strings, the 40 preheat scenario had the least loss of tension. And we saw in Figures 7 and 8 that stiffness is proportional to temperature. Figure 8 Closeup of stiffness vs temperature for each nylon and polyester string. As a result, a cold ball has a much lower bounce. As such, there tends to be a massive variation of temperature. Any type of extreme temperature, whether hot or cold, will cause undue wear on the strings. The Erector Spinae muscle causes trunk extension to allow the abdominals to fully flex the trunk and generate the force that is then transferred to the upper body. A string was secured between two clamps 200 mm apart at start and running through a clear perspex tube with rubber plugs in each end. Repeat this this step three times and record all of the results. Temperature causes the internal pressure of a tennis ball to change. An experiment was performed to determine the effect of temperature on the stiffness, elongation, tension loss and maintenance of tennis strings. This act is attained underhand or overhead. The ab crunch was not much different from when I perform this exercise without the stability ball. String materials vary in terms of their durability, given extreme weather conditions. cuz in my experiment i got some mixed up results. (Incorporation, 2011) This method was used for a long time. Now the equilibrium between the tension and the bonds is broken. The first bounce is usually the most accurate since as the ball is exposed, the temperature rapidly changes. Temperature Quadratic ANOVA, Table 13: Ball 1 vs. The setup was essentially the same as in Figure 1 but a computer controlled stretching program was different. Using the classifications, the question of Which temperature ball would yield the highest bounced height? would be answered. (Harriman, 2012)When the temperature increases, the gas molecules expand and as they expand, the energy of them increases, causing them to bounce more tempestuously. A complicating factor is that the ball also changes performance with temperature. The colder, the lower the ball bounces, and vice versa. Retrieved 8 24, 2012, from Wikipedia: http://en.wikipedia.org/wiki/Tennis_ball, Your email address will not be published. Time out of the can does pose a significant relationship, although that relationship can not be proven with the data from this experiment. After the tennis ball reforms into its original shape, the gas inside the ball pushes back up and causes the ball to bounce into the air. This increased accessibility to insights both on and off the court will help tennis players everywhere. Do you know what mechanics are really behind the outer layer? The balls which were placed in a freezer had a bounce percentage of 54.90. Ice chest with ice With such a low R squared value, the regression line does not predict many of the points and can not be considered a good fit to the relationship. As long as there is stress, some molecular bonds will continue to reorient to less stressful positions given enough time. This phase was similar to the pre-tensioning heating test but an additional 100 seconds was added to allow tension to stabilize. Once you have the right conditions under which to carry out your experiment, you can go ahead and start gathering the materials that will be needed. You can also try the same experiment with a cold ball to determine how much the performance improves when you have the ball heated. Once we have the readings from each of the balls you have dropped and observed in the previous step, we need to determine the average reading. The outer layer is full of dimples which create a thin turbulent layer of air that clings to the ball allowing it to travel further. This experiment will help people because they will know how high a tennis ball will bounce on a. Findings from University of Sydney Tennis Warehouse Study (2016), weather and environment can influence not only the way tennis strings. Energy Flow and Return Between a Tennis Ball and Stringbed, Free-standing vs Hand-held Racquet Testing. Some interesting results can be found in an analysis of the experiment results. Natural gut string is generally more responsive to changes in temperature. The colder air will also have molecules closer together, and they will also tend to be more inert in the sense that they will not be able to move around much. This machine measured string tension vs elongation. Tension is a component of stiffness. Synthetic materials hold up better, on the other hand. Figure 10 Closeup of elongation vs temperature for each nylon and polyester string. Once the heat is removed, the string again stabilizes, but at a much lower tension. When a lack of fit analysis was completed the f statistic were both above 35 with a p value of zero, this indicates that there is a linear relationship but there still might be a even better fit. On the other hand, the thermal energy of a warmer string helps break weak bonds between molecule chains, allowing greater flow and elongation of the string during stretching. But because stress relaxation occurs at varying rates both before and after achievement of target tension, the magnitude of tension loss during the relaxation period (i.e., after the racquet has been strung) does not necessarily correlate to the total relaxation that has occurred nor to the final stiffness of the string. A thousand seconds after achieving target tension and being clamped off, the string that took only 1 second to stretch to target tension lost almost 3 Kg more tension than the one that took 26 seconds. The tennis balls were left for 4 hours to adequately cool down. The green represents the felt on the ball, and the black represents the hollow core. The hypothesis was supported. With this, it will look at the movements that occur at each of the upper extremity together with the muscles that are in use at the joints. This will give you a visual presentation of the bounce heights and the temperatures, which means that determining whether hot or cold balls can bounce to a higher height will be a lot easier. Therefore, gas molecules can easily expand or contract. A normal tennis ball has a rubber core occupied with a gas that is composed of unorganized molecules or atoms that move around freely. Upon conclusion, I am to determine why resistance was limited during the activity. The molecules that make up gas are relatively unorganized; they readily slide around and over one another to fill up any space they occupy. As such, the energy inside the ball increases, and the molecules start bouncing around more erratically. Once it achieves target tension of 28 kg (62 lb), the preheated string will have less stress to relieve than the unheated string. With an increase in the temperature, the gas molecules within the tennis ball start to expand. While nylon and polyester are less durable than nylon and responsive to unfavorable conditions, they are still more robust than natural gut. The pressure of the gas inside of the tennis ball is what determines how high the ball will bounce. She works in a neonatal intensive care unit (NICU) and her previous nursing experience includes geriatrics, pulmonary disorders and home health care. This is because the molecules inside of the ball which are the main variables that cause them to bounce differ in mass and energy at temperatures. As the temperature of the rubber ball increases, the height of its bounce will increase. Generally, temperature affects a ball's resiliency, the spin and the density of the air through which the ball travels. It is also an ideal learning opportunity that can show us how the effects of temperature cause variations in the bouncing ability of a tennis ball. Each contributes to how a ball performs. 1a Heat before tensioning. Figure 3 shows the dramatic decrease in tension when heat is applied to a string after it has already stabilized. Conclusion. The "take-away" is twofold: First, if you like firm/stiff playing strings, do not expose them to higher than usual temperatures after stringing. The movement of the air and the squishing inwards when the ball has been dropped cause the ball to push out again, which is the reason for the bouncing movement. Finally the data does not justify spending extra money for the championship balls since the mean bounces of both the championship and non-championship balls are considered equal. It is the other way around for polyester the 20 string loses more tension than the 40 string. In order for maximum force to be generated, a tennis player needs a good stable base from where they can begin the movement. (2011). Ever felt that muggy feeling when it is particularly humid outside? In this experiment, one will put the tennis ball at four different temperaturesroom, freezing, hot, and cold. The thing that is changing is the temperature of the tennis ball. The regression Graphs 3, 4 show R squared values considerably higher than any of the time regression models. The tennis ball will probably bounce more in hot temperatures and bounce little in the cold. Average the results. To measure the bounciness of a ball, you can try dropping it from a height onto a hard surface. Heating before tensioning would simulate the effect of temperature during the stringing/tensioning process. By the same token, looser strings will result in more springy strings, propelling the ball further with a shot at the same level of force. Results for Setup #1 tension loss vs timing of heat application. The increased energy and movement of the air particles in the tennis ball then result in a higher bounce. Bocce ball was steadily rising and falling in popularity, until a major resurgence in 1896, when it was admitted an olympic sport, and has been part of the summer olympics ever since. Here is another table that shows the exact height in which the ball bounced. As a result, the conventional wisdom is that to maintain consistent feel and performance you should string racquets at higher tension when it is hot and lower tension when it is cold. I thank Dr. Choi for teaching me how to do this assignment and my parents for buying tennis balls for me. If the uniform temperature of a tennis ball is decreased, the balls bounce will be lower. Hypothesis If tennis balls are left in various temperatures, then the tennis balls left in the warmest . After the 20 minutes, take out the ball. Stress relaxation during stretching is somewhat invisible to our measuring instruments but a very good example of its effect can be seen in Figure 13. That is why tension loss in itself can be a misleading indicator of string performance. The paper will focus on the some of the types of the serves and the ways in which the upper extremity are involved in the game. 4.Tennis ball D was placed in the preheated oven for 90 minutes. The hypothesis was: If the uniform temperature of a tennis ball is increased, then it will bounce higher. Figure 7 is qualitative in that the horizontal axis is simply the itemization of each string, and thus each curve does not demonstrate any quantitatively causative relationships. This is due, in large part, to their construction. But how much higher or lower? Notebook Most players agree that in hot weather the string plays livelier and has more power due to tension loss and that in the winter, strings feel firmer and less powerful. (Incorporation, 2011)The spherical rubber would then be molded to an actual sphere in heated cavities.
