Bouncing balls coursework conclusion

From my results and graphs. I can now refer back to my hypothesis; I can see my prediction was correct. This is what I predicted in my hypothesis, because more potential energy is gained from a greater height. This signifies that my data is not accurate.

There is a linear relationship. You can also notice this in my graph because it is a line which always goes up, never down. The efficiency is calculated by looking at slope of the line of best fit.

I also noticed that in my graph the points are close to the Trendline. Which in the graph above. In my table the highest difference was 5 cm I think that wont create that much of a problem precision in my data. If the camera was held at and higher angle it would give me a lower height and vice versa.

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.

A graph showing the drop height and average bounce height with a trend line and an equation of best fit for tennis ball that was dropped on a concert floor. This made my data more precise because in the Slow Mo camera we could see the videos a few time and if we thought the ball fell on different heights we could get some else opinion to see which answer was right and we are also able to zoom in on the video to clear our doubts.

This made my data less precise since at different angles we see heights and if they are incorrect the whole point of the experiment in useless but the person tried to minimize the angle difference. One weakness of my investigation was the angle our camera was set on cause a person was holding it so Bouncing balls coursework conclusion angle of the camera might have varied.

In the future I could minimize this problem by using a tripod and the would eliminate the problem. This made my data less precise since the experiment we conducted was out side of a closed environment the air resistance was not the same at all times cause sometimes there would be is the wind and sometimes there would be no wind at all.

For further study relating to bouncing balls we could study how different surfaces affects the efficiency of the ball. 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.

The y- interpret that — 3. If there is no drop height there should be no bounce height which should be 0 cm. The graph shows that as the drop height increases the bounce also increases gradually. For further study relating to bouncing balls we could study how if we remove the air resistance and gravitational force affects the ball.

If there was more wind there would be a lower bonce height and vice versa. Another weakness of my investigation was the air resistance. The three trials for each bounce height were quite similar indicating a good precision in my data.

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.

We can find all this out using apps like excel and numbers either one works. In the future I could minimize this problem by conducting the experiment indoors and I would turn off the air condition to minimize it even more thus there will always be air resistance in the room but it will be the same so it wont mater that much.

I noticed that as I increase the drop height of the ball, the bounce height would also increase.Conclusion; Background and Bibliography This is because there weren't enough cross-links to hold the mixture together which prevented it from bouncing higher.

Imagine you have two nets and you stretch them as far as they can go. I could have given more variations of mixtures by making more balls and adding more borax so that I could. The Bounce Of A Ball Physical Education Essay. Print Reference this. Disclaimer: That is why different kinds of balls will bounce to different heights after they are dropped.

Variables. The variables in my investigation will be: Height from where the ball is dropped Conclusion. A bouncing ball constantly changes between kinetic energy. Introduction to the Scientific Method: Bouncing Balls Lab Bouncing Balls at Different Heights?

Polymer Balls, Meter Sticks, Masking or colored electrical tape for measuring and marking lines CONCLUSION: Effect of Bounce Height on Drop Height of a Ball (RULES FOR GRAPHS. In bouncing ball experiment, I measured time of contact with the ball and floor.

Using I=Ft=mv-mu equation I can calculate how much force is exert. Feb 24,  · This is a video I did for some A Level Physics Coursework.

We had to research a material of our choice, and I chose Polybutadiene, or the. Science Efficient Of A Bouncing Ball Lab Report.

Posted on 10/05/ by numairk. Efficient Of A Bouncing Ball Lab Report For further study relating to bouncing balls we could study how if we remove the air resistance and gravitational force affects the ball.
