Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What is Potential Energy?

Back

Potential energy is stored energy that has the potential to do work. It is often associated with the position of an object.

Front

At which point is Kinetic Energy greatest in a pendulum swing?

Back

Kinetic energy is greatest at the lowest point of the swing.

Front

At which point is Potential Energy greatest in a pendulum swing?

Back

Potential energy is greatest at the highest points of the swing.

Front

What type of energy does a moving skateboard have?

Back

A moving skateboard has kinetic 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 is the formula for Kinetic Energy?

Back

The formula for kinetic energy 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 is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

Can an object have both Kinetic and Potential Energy?

Back

Yes, an object can have both kinetic and potential energy at the same time, such as a ball at the top of a hill that is about to roll down.

Front

What is an example of Potential Energy?

Back

An example of potential energy is a stretched rubber band or a book on a shelf.
