Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

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 edge of a cliff has potential energy.

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

Give an example of Kinetic Energy.

Back

A moving skateboard is an example of Kinetic Energy.

Front

Give an example of Potential Energy.

Back

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

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 type of energy does a person climbing a ladder have?

Back

A person climbing a ladder has both Kinetic Energy (due to movement) and Potential Energy (due to height gained).

Front

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and Potential Energy can transform into each other. For example, when an object falls, Potential Energy converts to Kinetic Energy.

Front

What is an example of energy transformation?

Back

When a roller coaster goes down a hill, its Potential Energy is transformed into Kinetic Energy.
