Physics drop bounce lab report

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 closer the coefficient is to one, the bouncier the object is.

Your review will show that in most mechanical systems the total energy is the sum of the potential energy and the kinetic energy. If you hold out your hand and drop the ball, with how much energy does it start?

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.

How much of that energy is kinetic and how much potential? The total energy slightly decreases also due to the inelasticity of the bounce. 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.

Use them to answer your aim. I noticed that as I increase the drop height of the ball, the bounce height would also increase. You will find it convenient but not necessary to know the mass of each of these balls.

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. Our independent variable will be the drop height, measured in feet. You can also do the experiment on different surfaces.

Depends from where you measure the heights. Answer to the questions are given at the end of this exercise, but you should try to answer them before looking.

Be sure to insert a graph see how herebecause the eye picks up trends and patterns more easily from a diagram than it does from a table of numbers, plus trend lines can be drawn to extrapolate and interpolate data. An object with a coefficient close to zero would have very little bounce.

What are the implications of your findings for commercial wind mills? How reliable do you think your results were? Go up Problem The purpose of this investigation is to find the relationship between drop height and the coefficient of restitution of various sports balls.

After it bounces back up to its greatest height, how much kinetic and potential energy does it have then? 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.

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. If there was more wind there would be a lower bonce height and vice versa.

One of the strength of this investigation was that we used a slow Mo camera. During the motion of the ball, kinetic energy is not being conserved but rather distributed into the ground.

This trend implies that shorter drop heights are more efficient than larger drop heights. Of course, it does not.

Another weakness of my investigation was the air resistance. 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. What actual measurements do you take?

You should be able to find this in your introduction. There is a linear relationship. I also noticed that in my graph the points are close to the Trendline. Go up Hypothesis We believe that as the drop height increases, the coefficient of restitution will stay the same.

Do you get the same answer each time you do the experiment? Find the percentage of mechanical energy lost for each ball during one bounce and estimate the precision of your result. This is because potential energy is lowest when the ball hits the ground.Essays - largest database of quality sample essays and research papers on Physics Drop Bounce Lab Report.

Lab Freefall: Timing a Bouncing Ball. When the balls is dropped, the student with the stop watch listens for the sound of the first bounce, starts the stop watch, and then listens for the sound of the second bounce, when he immediately stops timing.

A team may submit its data report online together. No papers need to be turned in to the.

Science Efficient Of A Bouncing Ball Lab Report

Physics Ball Drop Lab Report Kathryn Marchessault Physics Lab LR Tuesday Due 02/26/15 Experiment #1 Free Fall Experiment Abstract In this experiment we studied the motion of an object in free fall, that is an object being dropped from a certain height to Earth’s surface In this experiment we tested the idea that no matter what the size.

Aug 05,  · Learn how the height a ball is dropped relates to how high it bounces. Collect the data, and visualize it on a graph.

Bouncy ball lab report. Introduction and research In this lab I made 2 malleable like bouncy balls from a few simple ingridients and instructions to make it. The first ball made didn't bounce at all, but the second one did.

Purpose and problem. Physics Biology Earth Sciences Junior High school level. During the early years of junior high school you may be required to write a practical report for an experiment, or an extended experimental investigation (an experiment that takes you a number of days to complete).

The effect of changing the drop height on the bounce efficiency is.
