The ball squashes essay

The ball squashes Aim — To investigate how the height a ball is dropped from affects the re-bounce of it. Equipment — 1 meter ruler stick — I chose this because it was more accessible and something else like a tape measure would not be reliable as it is not solid and can move more easily. Resistance… Beakers and measuring Chemical engineers exploit chemical reactions to produce materials on a commercial scale. One of their principal activities is the design and operation of chemical reactors.

All the other calculation were done like this. The three trials for each bounce height were quite similar indicating a good precision in my data. In my table the highest difference was 5 cm I think that wont create that much of a problem precision in my data.

My data is also very consistent according to my table for example when the drop height was 80 cm and the bounce height for the first trial was 50cm and for next on it was 51cm and the next one was 50cm as we see these numbers are very close to each other and that means my data is precise.

A graph showing the drop height and average bounce height with a trend line and an equation of best fit for tennis ball that The ball squashes essay dropped on a concert floor.

The graph shows that as the drop height increases the bounce also increases gradually. From my results and graphs. I noticed that as I increase the drop height of the ball, the bounce height would also increase.

This is what I predicted in my hypothesis, because more potential energy is gained from a greater height. You can also notice this in my graph because it is a line which always goes up, never down. There is a linear relationship. The y- interpret that — 3. This signifies that my data is not accurate.

If there is no drop height there should be no bounce height which should be 0 cm. I also noticed that in my graph the points are close to the Trendline. The efficiency is calculated by looking at slope of the line of best fit.

Which in the graph above. We can find all this out using apps like excel and numbers either one works. I can now refer back to my hypothesis; I can see my prediction was correct.

That the higher the drop height of the tennis balls the higher the bounce height. I have also proved that more potential energy is gained from a greater height and that the ball will NEVER bounce to the original drop height because following the Law of Conservation of Energy states that energy cannot be created or destroyed, but can be transformed.

So the ball is raised to a certain height the potential energy in the tennis ball is there and when it is dropped it turns into kinetic energy is wasted to sound, heat movement, ball compression, etc. It was expected that the bounce height will increase as drop height increases, but will not be quite as high as the original drop height and the resulting bounce efficiency will remain relatively consistent throughout the drop height range.

This was because as the ball was dropped from greater heights the gravitational potential energy increased simultaneously, which could then be converted back into kinetic energy as the ball bounced back.The Sport of Squash - The Sport of Squash In this essay the sport squash will be looked at, at a local level for me and at higher levels through the .

Get the tennis ball and the hold the ball at 50 cm make sure that the bottom of the ball is at 50cm and when you drop the ball tell your partner to record the ball bouncing and when the ball is not bouncing stop recording.
