Investigating the Effects of Temperature on the Bounce Height of a Squash Ball
Aim:
How temperature affects the bounce height of a squash ball.
Prediction:
I predict that the warmer the squash ball is the higher the bounce
height of a squash ball will be.
Apparatus:
* water from a kettle
* kettle
* ruler
* clamp
* clamp stand
* beaker
* squash ball
* thermometer
Diagram:
Method:
§ Collect all the equipment needed for this investigation.
§ Set up the equipment as shown in the diagram.
§ Pour water from the kettle into the beaker until it is half full and
put a thermometer in the beaker to measure the water's temperature.
§ Put the squash ball in the beaker for a set amount of time and take
down how warm the water is by looking at the temperature reading.
§ Decide on a drop height for the squash ball. Use this drop height
throughout the whole investigation.
§ Write down how high the squash ball bounces.
§ Record the bounce height in a results table alongside the squash
ball's temperature.
§ Put the ball back in the beaker.
§ Repeat this method another seven times.
§ Each time drop the squash ball from the same height but the squash
ball should be at a different temperature each time it is dropped.
§ Once you have collected all your results draw a graph showing your
results.
Scientific Theory:
Gravity made the ball come down when it was dropped. There was a
little friction on the bounce surface as it was not smooth. Energy was
lost ion the form of heat and sound energy. The squash ball did not
bounce back to its drop height because energy was lost as heat
and sound energy.

Investigating the Bounce of a Squash Ball This investigation is associated with the bounce of a squash ball. I will be investigating 4 different types of squash balls, which have different, bounce properties and compare them to each other and relate them to why each different type of squash ball is used. The relationship will be associated with how different balls are used at different levels of proficiency in the game of squash i.e. the squash balls that don't bounce much will probably used at a less proficient level whereas the balls with the most bounce will be used at professional level. The different coloured squash balls I will be using are; white, yellow, red and blue, and I will be finding out what the difference is between them.
Start with the hot water and first measure the temperature. Record it. 8. Then pour 40 ml into the beaker. You can measure how much water was used by looking at the meniscus.

3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.
How does the material of a ball affect the bounce height/vertical motion of that ball?
Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. The first independent variable that will be tested.
2. In the large beaker, put water and boil it completely. After that, remove the beaker from heat. 3. Sample tubes (A-D) should be labeled and capped tightly.
There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.
