2. Open question

210 seconds

In the Pendulum lab, you observed the shorter the string, the more swings the pendulum made in 10 seconds. Explain why you think this occured.

3. Open question

Why doesn't the pendulum return to it's orginal starting height?

4. Drawings

450 seconds

Draw a model of the pendulum in motion. Label it with the following: 100% PE, 50% PE, 20% PE 100% KE; 50% KE, 80% KE *Hint- there should be 7 labels total
