Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object has 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 top of a hill has potential energy.

Front

Where is Potential Energy greatest on a roller coaster?

Back

At the top of a big hill.

Front

Where is Kinetic Energy greatest on a roller coaster?

Back

At the bottom of a big hill.

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 the acceleration due to gravity, and h is 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 is Energy Transformation?

Back

Energy Transformation is the process of changing energy from one form to another, such as potential energy to kinetic energy.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a running dog, or a thrown ball are all examples of kinetic energy.

Front

What is an example of Potential Energy in everyday life?

Back

A stretched rubber band, a book on a shelf, or water stored in a dam are all examples of potential energy.
