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. 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

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 Gravitational Potential Energy?

Back

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

Where is maximum Kinetic Energy on a roller coaster?

Back

Maximum Kinetic Energy is at the bottom of a big hill.

Front

Where is maximum Potential Energy on a roller coaster?

Back

Maximum Potential Energy is at the top of a big hill.

Front

What type of energy does a moving skateboard have?

Back

A moving skateboard has Kinetic Energy.

Front

At what position does a rock have the greatest Kinetic Energy?

Back

A rock has the greatest Kinetic Energy at the lowest point of its path.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more Potential Energy it has, because GPE increases with height.

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with mass; a heavier object moving at the same speed has more Kinetic Energy.
