1. Why does a pendulum work well to demonstrate the law of the conservation of energy?
2. Why doesn’t the pendulum (in the video it’s a bowling ball) hit the student?
3. What would happen if the student pushed on the bowling ball instead of just letting it go?
4. What is the “principal of the conservation of energy”?
5. Draw the path of the pendulum (bowling ball) and label the parts of the path where there is
potential energy and kinetic energy. (You can draw it on paper, take a picture with your phone, and send it to me).

7 = Steve's velocity (1.5 m/s) and that of the walkway (0.5 m/s) combine for a total velocity of 2.0 m/s

8 = Steve and the person on the walkway share a frame of reference because they are both on the moving walkway. To Steve, the person who is standing still on the walkway seems not to be moving. To that person, Steve is moving forward at 1/5 m/s

9 = Steve and the woman sitting beside the walkway do not share a frame of reference because he is on the moving walkway and she is not. The woman will see Steve pass her at the combined velocities of Steve and the walkway: 1/5 m/s + 0.5 m/s = 2.0 m/s
