Potential and Kinetic Energy Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to do work when released.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

When is potential energy at its highest in a roller coaster?

Back

Potential energy is highest at the top of a hill.

Front

When is kinetic energy at its highest in a roller coaster?

Back

Kinetic energy is highest at the bottom of a hill.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy.

Front

What type of energy does a moving car have?

Back

A moving car has kinetic energy.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with the mass of the object; more mass means more kinetic energy.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed; doubling the speed quadruples the kinetic energy.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.
