I noticed that as I increase the drop height of the ball, the bounce height would also increase. A seemingly mundane but significant aspect of this work was the new ability to feed the result of one computation into the next and print the results of these calculations directly, thus eliminating the transcription errors that were common in astronomical and lunar tables [ 17 ].
And feels solid and reliable.
If you review those concepts, you will be better prepared for this experiment. You will work on this throughout the year. Keep up the good work. Move your arm up and down and send waves down the string or cord.
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. Each time the object falls it loses potential energy and each time it returns it gains potential energy.
He used a vacuum to take out the air. M Read about this experimentwatch the video and try it if you have what you need. One of the strength of this investigation was that we used a slow Mo camera.
Answer to the questions are given at the end of this exercise, but you should try to answer them before looking. If the balls are ranked according to the percentage of energy lost, do different surfaces change the ranking? Need an idea of what to put inside about hydrogen? The ball was then dropped and the rebound was measured by eye at approximately 90 degrees to the ruler to minimise parallax errors.

One way to do the experiment is to put a mark on the wall at a measured height with the aid of your string if necessarydrop the ball from that height and measure the rebound. This could be due to the limits of the tennis ball to store kinetic energy as elastic potential energy because it requires increasingly greater amounts of force is to continue to squash the ball by the same amount when it lands.
The results of the experiment support the hypothesis that as drop height increases, so too will the bounce height due to an increase in gravitational potential energy, however the bounce efficiency remained relatively consistent.
While it is a great alternative for designers who are with short time and produce things for small customers. Record in your science notebook the different ways you vibrated molecules to create sound.
The total energy is the sum of both the kinetic and potential energy. If you have a grape and a microwave, then you can create plasma.
The tennis ball was then dropped from various heights; 1, 1. Each one had a Marchant. Because the experiment did not use a perfectly elastic surface, we can be fairly sure that the bounce was the actual cause of the loss of total energy, rather than the air resistance.
Diagram of apparatus Boman, List as many variables involved as possible in your table above. To estimate the uncertainty in your answer you might want to repeat the experiment a second time.
Potential energy is dependent upon the mass of the object, acceleration due to gravity and the height of the object.
The only one who could fix them promptly was Richard Feynman Nobel Prize in Physics,which some thought was not the best use of his time. The graph shows that as the drop height increases the bounce also increases gradually. When molecules cool down, they slow down to mostly stopped.
How much of that energy is kinetic and how much potential? 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.
When a train came to a city, it brought more people. The advertisements are just to get your money. Color where the steam is red.
For example by heating the solid ice you change it into a liquid. Label your picture and keep it in your science notebook. Ice, water and steam are all H2O. Good work mobirise team. If there is no drop height there should be no bounce height which should be 0 cm.
Click on Nanolab and Build.Sample Lab Report: Please note: This is a fairly nice lab report of an experiment that should provide a guide to you for producing your own lab reports.
we held the ball below the sensor enough so its position is recorded and we began the recording and let the ball drop. Each bounce created a total energy loss of approximately J.
Note that La Nina cooling in the tropics has finally penetrated the troposphere, with a deg. C departure from average. The last time the tropics were cooler than this was June, ( deg.
C). Out of the month satellite record, the deg. C one-month drop in January tropical. Get the latest science news and technology news, read tech reviews and more at ABC News. in this part of the lab, you will drop your tennis ball from each of the heights that you recorded in boxes 1, 3, 5, 7 on your data sheet bounce (lab part two: velocity box c): _____ kinetic energy of fall after 2nd “bouncing ball” lab data sheet.
If _____ then _____ because _____. To see more on this, visit Writing better hypotheses and methods If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.
This is a fairly nice lab report of an experiment that should provide a guide to you for producing your own lab reports. It was written by students who took this course. we held the ball below the sensor enough so its position is recorded and we began the recording and let the ball drop.
