Potential & Kinetic Energy

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

Give an example of Potential Energy.

Back

A book on a shelf has Potential Energy because of its height above the ground.

Front

Give an example of Kinetic Energy.

Back

A moving car has Kinetic Energy due to its motion.

Front

What happens to Potential Energy when 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

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 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

How does height affect Potential Energy?

Back

The higher an object is, the more Potential Energy it has, because it has the potential to fall further.

Front

How does mass affect Kinetic Energy?

Back

The more mass an object has, the more Kinetic Energy it has at the same speed.

Front

What is gravitational Potential Energy?

Back

Gravitational Potential Energy is the Potential Energy an object has due to its height in a gravitational field.
