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. For example, a car parked on a hill has potential energy because of its height.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. For example, a moving car or a rolling ball has kinetic energy.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more potential energy it has. For example, a kid at the top of a sledding hill has more potential energy than at the bottom.

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

Give an example of an object with Kinetic Energy.

Back

A school bus leaving the school is an example of an object with kinetic energy because it is in motion.

Front

What is the relationship between Potential and Kinetic Energy?

Back

Potential energy can be converted into kinetic energy. For example, when a roller coaster descends from a height, its potential energy converts to kinetic energy.

Front

What is an example of Potential Energy in everyday life?

Back

Holding a marble at the top of a ramp is an example of potential energy because it is stored energy due to its position.

Front

What is the formula for calculating 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 calculating 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 mass affect Potential Energy?

Back

The more mass an object has, the more potential energy it has at a given height. For example, a heavier object at the same height has more potential energy than a lighter one.
