Activity 1.3. Energy in Action
Objective: Describe kinetic energy.
Materials: Table, rubber ball, stopwatch (cellphone with stopwatch)
Procedure:
1. Get a table.
2. Place the rubber ball on the side of the table.
3. Push the rubber ball.
4. Using a stopwatch, measure the time for the rubber ball to reach the other side of the table.
5. Observe the movement of the ball.
Questions
1. Based on your observation, what causes the ball to move?
