Notes: What is Energy? Stop and Jot. On the top of your notes write down: where have you heard the word energy before? What do you think it means?

Notes: What is Energy? Energy is anything that can cause matter to change. Hitting a baseball, holding a book above your head, digesting food and heating water all take energy!

Energy There are two types of Energy: Kinetic Energy Potential Energy

Energy In these two types, there are many different forms of energy: Chemical, mechanical, sound, heat, light, electrical, nuclear, gravitational, and elastic.

BrainPop Listen for the different types and forms of energy.

Potential and Kinetic Energy

What is Energy? Anything that can cause a change in matter.

Two Types of Energy: Kinetic Energy Potential Energy

Potential Energy 1. Potential Energy is stored energy. 2. An object with potential energy has the ability to move or change.

Potential Energy 3. Potential energy depends on an object’s position or condition. Example:

Examples:

Brainpop 2 Listen for the different types and forms of energy.

Kinetic Energy 4. Kinetic Energy is the energy of movement. 5. It depends on the mass and speed of a moving object.

Examples:

PE and KE Lab! Follow all directions carefully. Be sure you test each marble position twice. Answer your conclusion questions when your group finishes.

Discussion When did the marble have the most potential energy? When did the cup move the farthest? What did this show you about potential and kinetic energy?

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.
