Name:Kinetic and Potential Energy

Part One:1.) Predict how you will think changing the mass on the end of the pendulum will affect howmany times it swings back and forth in one minute:

2.)

3.)4.)s.)

Decide how many weights you and your group will use for Trial l. Use multiples of 20(20, 40,60, 80...) Each 20 weights has a mass of 50 g.Record how many weights your group is using:Place the weights on the ring. Attach the ring to the lowest gold ring on the pendulum.Pull the pendulum back so the weights are I meter from where they started. This is yourstarting position.

6.) Let go of the pendulum. As soon as you let go, start timing for one minute. Count thenumber of times the pendulum swings back and forth. Record this information in thetable below for Trial I.7.) Repeat this two more times.8.) Change the number of weights your group is using for Trial2. Record the number:

six and seven. Fill in the table each time.Part One

10.) Calculate the average number of swings and the average time. (To calculateaverage, add the three numbers together and divide by 3)

Part Two1.) Predict how you think changing the height of the mass will affect the number of times thependulum swings back and forth in one minute:

2.) Place 40 weights on the ring. Attach the ring with the weights to the gold ring on thebottom.3.) Measure the height from the floor to the ring using feet. Record this in the Height Table.4.) Pull the ring back so that it is one meter from where it staned.5.) Let go of the pendulum. As soon as you let go, start timing for one minute. Count thenumber of times the pendulum swings back and forth. Record this information in the

table below.6.) Repeat this two more times.7.) Move the weights to the smallest ring. Use the binder ring to hold the other rings up.

Repeat steps three to six.8.) Move the weights to the largest ring. Use the binder ring to hold the other rings up.

Repeat steps three to six.9.) Move the weights to the top ring. Use the binder ring to hold the other rings up. Repeat

Questionsl.) In part one, does your data support or not support your hypothesis?

2.) What aflect did changing the mass have on the speed of the swings?

3.) In part two, does your data support or not support your hypothesis?

4.) What affect does the length of the pendulum have on the speed of the swings?

5.) Think of the school. There are several objects that move like a pendulum. What is oneof them? (Hint: Thhk Playground. ..)

6.) As you were counting swings, what happened to the speed of each swing?

7.) What is potential energy?

8.) Where does the pendulum have the most potential energy?

9.) What is kinetic energy?

10.) Where does the pendulum have the most kinetic energy?1 1.) Where does the pendulum have the least potential energy?
