1. oneone EEM-1B Objective: To analyze the movement of an object in order to explain the Law of Conservation of Energy CSI Note: Can energy be created or destroyed? Drill: 1. Take out a clean sheet of paper. 2. Title the paper, “Potential and Kinetic Energy”. 3. Number the paper from 1 – 20.

2. oneone EEM-1B Activity 1: Kinetic and Potential Energy – Can you tell the difference? Observe the PowerPoint presentation. For each slide write “P” if potential energy is being described or “K” if kinetic energy is being described.

3. oneone EEM-1B Law of Conservation of Energy How can you create energy? How can you destroy energy?

4. oneone EEM-1B Explore the following web page: http://www.walter-fendt.de/html5/phen/pendulum_en.htm

5. oneone EEM-1B What energy conversion takes place as a pendulum swings from the high point to the low point? Energy is converted from potential to kinetic as the bob loses height and gains velocity.

6. oneone EEM-1B What energy conversion takes place as a pendulum swings from the low point to the high point? Energy is converted from kinetic to potential as the bob gains height and loses velocity.

7. oneone EEM-1B Video: https://www.youtube.com/watch?v=_uLSFigtLKg Listen for both parts of the “Law of Conservation of Energy”

8. oneone EEM-1B Law of Conservation of Energy 1. Energy cannot be created or destroyed. 2. Energy may only be transformed from one form to another.

9. oneone EEM-1B Think – Pair – Share Open Discussion If energy cannot be created or destroyed, why does a pendulum eventually stop? What happens to the energy?

10. oneone EEM-1B When two objects or substances come into contact with each other, friction occurs. Friction generates heat. The energy of motion is transformed into the energy of heat.
