Potential and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. For example, a rolling ball or a moving car has kinetic energy.

Front

What happens to energy when an object falls?

Back

When an object falls, its potential energy is converted into kinetic energy as it gains speed.

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating Potential Energy?

Back

The formula for Potential Energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be converted from one form to another.

Front

What type of energy does a battery store?

Back

A battery stores Potential Energy.

Front

Which has more Potential Energy: a baseball held high or a baseball on the ground?

Back

A baseball held high has more Potential Energy than a baseball on the ground.

Front

What type of energy does a moving car have?

Back

A moving car has Kinetic Energy.

Front

What is an example of Potential Energy in everyday life?

Back

An example of Potential Energy is water stored in a dam.
