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.

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.

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

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.

oneone EEM-1B Video: Listen for both parts of the “Law of Conservation of Energy”

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.

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?

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.
