Therefore, I came up with the idea of putting the squash ball in a beaker of water, and heating this in a flame.
Online Plagiarism Checker Kinetic energy - Sample Essay Introduction For my physics coursework, I have been asked to investigate the factors which affect the way in which a squash ball will bounce. I looked into a few different factors, including; Heat of the ball, landing surface of the ball, and in depth: To observe how the height a ball is dropped from affects the height the ball bounces back to, we put a meter stick against a wall, with another one directly above it two meters tall.
We then held the ball so the bottom of it aligned with the height we were planning to drop it from. Meanwhile, another member of our team was lying on the floor facing the meter stick, and observed, from ground level, how high the ball rebounded.
We dropped the ball at.
One more thing we did to try and enforce a fair test was to heat the ball to 40 degrees Celsius after every five drops. I believe that this could be due to one, or both, of the following reasons: The air inside the hollow, airtight ball is trapped. When air is heated the distance between the molecules increases, and therefore the amount of pressure within the airtight ball increases.
Quite how this could affect the height of the ball would require a lot more detailed research.
The molecules of rubber which the ball consists of may become more flexible when heated, and therefore give the ball a little extra elasticity, thus giving more Elastic Energy at stage 3ii in my diagram.
Again, just how this works would require more research. Different Surfaces Balls bounce different heights off of different surfaces. I believe this is because a soft surface absorbs a lot more energy from the ball, thus giving the ball less energy to bounce back with.
In contrast, a hard surface would not absorb a lot of energy from the ball, so the ball would have more energy to bounce up. If my theory is true, a ball dropped from a fixed height i.
I could not test this theory because the time was limited.
The higher the ball is being held the higher the amount of Epg it will have at this point For example If the ball was held at 80 cm or 0.
At this point, the ball has Kinetic Energy.One dot or two? Yellow or red? Big or small?
Choosing the correct squash ball can be confusing, especially for squash newbies! We've tried to simplify the science to help you choose the right ball for your play. Squash balls come in different sizes and different colours and for a reason – they. πηvr.
Where η= the viscosity of the fluid.. From this formula, we can see that the viscous drag on the bigger ball is bigger than the viscous drag on the smaller ball. This is because the velocity increases as well as the radius.
How To Choose The Correct Squash Ball Squash balls are unique in that they need hitting for a few minutes until they ‘warm up’. It is important to choose the right ball for your level so that the ball stays warm and lively during play. Squash is a ball sport played by two (singles) or four players (doubles squash) in a four-walled court with a small, hollow rubber ball.
The players must alternate in striking the ball with their racquet and hit the ball onto the playable surfaces of the four walls of the court. is and in to a was not you i of it the be he his but for are this that by on at they with which she or from had we will have an what been one if would who has her.
