Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity)

Front

What is the formula for potential energy?

Back

PE = mgh (where m is mass, g is acceleration due to gravity, and h is height)

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position.

Front

What happens to kinetic energy when speed doubles?

Back

Kinetic energy increases by a factor of four.

Front

What is an example of potential energy?

Back

A rock held at the top of a hill.
