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. For example, a rock at the top of a hill has potential energy.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy depends on two factors: speed and mass of the object.

Front

Where is Potential Energy maximum on a roller coaster?

Back

Potential Energy is maximum at the top of a big hill on a roller coaster.

Front

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

Back

A rock has the greatest Kinetic Energy at the bottom of its fall.

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

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

What type of energy does a baseball held by a pitcher have?

Back

A baseball held by a pitcher has Potential Energy.

Front

What is the relationship between height and Potential Energy?

Back

The higher an object is, the more Potential Energy it has due to its position.
