Potential and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the stored energy 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 and velocity of the object.

Front

Give an example of Potential Energy.

Back

A basketball held in a player's hands has Potential Energy due to its height above the ground.

Front

Give an example of Kinetic Energy.

Back

A rolling ball has Kinetic Energy because it is in motion.

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 is the formula for Kinetic Energy?

Back

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

Front

What is the formula for Potential Energy?

Back

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

Front

At what point is Potential Energy greatest in a free-falling object?

Back

Potential Energy is greatest at the highest point before the object begins to fall.

Front

At what point is Kinetic Energy greatest in a free-falling object?

Back

Kinetic Energy is greatest just before the object hits the ground.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has Potential Energy due to its position.
