Potential and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It has the potential to do work when released.

Front

What is Kinetic Energy?

Back

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

Front

Give an example of Kinetic Energy.

Back

A tennis ball rolling across the court is an example of Kinetic Energy.

Front

What type of energy does an acorn hanging from an oak tree possess?

Back

An acorn hanging from an oak tree possesses Potential Energy.

Front

What type of energy does a rock at the edge of a cliff possess?

Back

A rock at the edge of a cliff possesses Potential Energy.

Front

At which point is Potential Energy greatest in a system?

Back

Potential Energy is greatest at the highest point in a system.

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 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 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 an example of an object with high Potential Energy?

Back

A car parked on a steep hill has high Potential Energy due to its elevated position.
