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 rock at the top of 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

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 speed.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by mass and speed. The greater the mass or speed of an object, the more kinetic energy it has.

Front

What is an example of an object with Kinetic Energy?

Back

A tennis ball rolling across the court is an example of an object with kinetic energy.

Front

What is an example of an object with Potential Energy?

Back

A rock at the edge of a cliff is an example of an object with potential energy.

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 potential and kinetic energy.

Front

At which point is Kinetic Energy greatest when an object is in motion?

Back

Kinetic Energy is greatest at the lowest point of its path, where speed is highest.

Front

What is the relationship between mass and Kinetic Energy?

Back

The relationship is direct; as mass increases, kinetic energy increases if speed remains constant.
