Kinetic and Potential Energy_Langley

Front

What is potential energy?

Back

Potential energy is the energy stored in an object based on its position or state.

Front

What factors determine potential energy?

Back

Potential energy is determined by an object's height and mass.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What factors determine kinetic energy?

Back

Kinetic energy is determined by an object's mass and velocity.

Front

How can you tell if something has energy?

Back

You can tell if something has energy if it moves, gives off heat, light, or sound.

Front

What is an example of kinetic energy?

Back

Swinging a baseball bat is an example of kinetic energy.

Front

What is an example of potential energy?

Back

A rollercoaster at the top of a hill has 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 is the relationship between kinetic and potential energy?

Back

Kinetic and potential energy are forms of mechanical energy; they can convert into each other.

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.
