Day 2: Potential and Kinetic Energy

What is Energy?•Anything that can cause a

change in matter.

Two Types of Energy:1) Kinetic Energy2) Potential Energy

Potential Energy1. Potential Energy is stored energy.2. An object with potential energy has the ability to move or change.

Potential Energy3. Potential energy depends on an object’s position or condition.Example:

Examples:

Kinetic Energy4. Kinetic Energy is the energy of movement.5. It depends on the mass and speed of a moving object.

Examples:

How are Potential Energy and Kinetic Energy related?

• Energy can be transferred from potential to kinetic energy.• If an object has more potential

energy to start, then it will have more kinetic energy when it starts moving.

Homework•On a blank sheet of paper,

draw two pictures of situations showing potential energy and two pictures of situations showing kinetic energy. Explain in words why each situation shows that type of energy.
