Potential & Kinetic Energy

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 because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by moving electrical charges. It powers devices and appliances.

Front

What is sound energy?

Back

Sound energy is the energy associated with the vibration of matter, transmitted through longitudinal waves.

Front

What happens to kinetic energy when an object comes to a stop?

Back

When an object comes to a stop, its kinetic energy becomes zero.

Front

Give 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 the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What is the formula for 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 an example of potential energy?

Back

A car parked on a steep hill has potential energy due to its elevated position.

Front

When does an object have no kinetic energy?

Back

An object has no kinetic energy when it is at rest.
