What would have the greatest kinetic energy?

• A car driving down a hill.
• A person running down a hill. 
• A ball rolling down a hill. 

Which is the best example that something has kinetic energy?

• a. a car parked on a steep hill 
• b. a tennis ball rolling across the court
• c. a picture hanging on the wall 
• d. a piece of coal before it's burned 

What is energy?

• something that picks up things, like a magnet.

• Motion of an object

• ability to do work

• magic rays of sunshine that come down when you're feeling blue.

What is kinetic energy?

• energy of work
• energy of motion
• energy of gravity
• energy of power

An object that is moving has

• chemical energy

• chemical energy

• potential energy

• kinetic energy

• elastic energy

If you are rolling down a big hill you are ____________ the kinetic energy.

If you are rolling down a big hill you are ____________ the potential energy.
