1. Bouncing Balls Lab

2. Purpose and Equipment
In this lab you will be investigating how energy is converted from one form to another.
You will need the following:
A tennis ball, wiffle ball, and hard yellow ball
A black plastic box
A meter stick with centimeters

3. Procedure READ THE STEPS WRITTEN IN THE LAB
-Instead of doing each trial “3” times, we’re going to do it “2” times.
Remember, you are recording the HEIGHT of the ball AFTER it bounces

4. Gravitational Potential Energy
GPE= mass of ball X 9.8m/s2 X 1 meter
Use the scale in the room to find mass of each ball.

5. Average Remember the average = (a+b+c+…)/ number of items.
In this case, you have two heights per trial, so (A+B)/2

6. Graph Go to chemislife.weebly.com Physical science Labs
“how to put a graph on google sheets”
Use this to help you make your graph. I will be here to help you as always, but I expect you to be able to work independently

7. Graph continued
Part of your grade will be making a graph that compares the GPE of each ball to the average bounce height.
Make two graphs, one for the floor trials and one for the box trials.
