Unit 5 Lesson 1 What Is Energy?
Energy All Around
Energy is the ability to cause changes in matter.
Energy can transform, or change, from one form into another.
Energy is never used up. It just changes form.

4. The Ups and Downs of Energy
Unit 5 Lesson 1 What Is Energy?
The Ups and Downs of Energy
Potential energy (PE) is the energy an object has because of its position or condition.
Kinetic energy (KE) is the energy an object has because of its motion.
PE is stored energy. KE is energy of motion.

6. Unit 5 Lesson 1 What Is Energy?
Loud, Soft, Hot, Cold
Sound energy is a form of energy that is carried as waves in vibrating matter.
Sound energy is a type of kinetic energy, because particles of matter are moving.
Sound energy is the cause of all the sounds you hear.

7. Unit 5 Lesson 1 What Is Energy?
Loud, Soft, Hot, Cold
Thermal energy is the total kinetic energy of the particles that make up a substance.
You can sense thermal energy as temperature.
The more thermal energy an object has, the greater its temperature.

Light energy is a form of energy that can travel through space.
Light energy travels as waves.
Some objects give off light. Other objects reflect light.

10. Energy in Machines and Food
Unit 5 Lesson 1 What Is Energy?
Energy in Machines and Food
Mechanical energy is the total energy of motion and position of an object.
Mechanical energy = KE + PE
Machines use mechanical energy to do work.

11. Energy in Machines and Food
Unit 5 Lesson 1 What Is Energy?
Energy in Machines and Food
Food contains energy.
Chemical energy is energy that is stored in matter and that can be released by a chemical reaction.
When your body breaks down food, potential chemical energy is released, producing heat.

12. Unit 5 Lesson 1 What Is Energy?
Spotlight on Energy
Musicians and performers rely on different forms of energy to complete their shows.
Potential, kinetic, chemical, light, heat, mechanical, and sound energies are used.
