Energy is the ability to…

• make heat

• do work

• Transform

What is potential energy?

• Energy an object has because it is in motion

• Energy stored in an object as a result of its position or state

Can you identify if the image is an example of potential or kinetic energy?

• Potential energy (P)

• Kinetic energy (K)

What is the Law of Conservation of energy?

• energy can be created but not destroyed

• energy can be destroyed but not created

• energy can neither be created or destroyed

Name these three forms of energy.

• Nuclear, Elastic, Chemical

• Thermal, Electrical, Sound

• Solar, Wind, Hydro

Match the form of energy to the correct example.

• Mechanical

• inside an oven

• Thermal

• turning a doorknob

• Chemical

• coal

When you catch a moving ball, what happens to the kinetic energy?

• it is destroyed

• it is transferred to your hand

Name an example of energy transfer.

• A ball rolling down a hill

• A book on a table

• A closed box

• A stationary car

Name an example of energy transformation.

• A battery powering a flashlight

• A book on a table
