Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

Give an example of Kinetic Energy.

Back

A boy running around a track is an example of Kinetic Energy because he is in motion.

Front

Give an example of Potential Energy.

Back

An apple hanging from a tree is an example of Potential Energy because it has the potential to fall due to gravity.

Front

What happens to Potential Energy when 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 (KE) 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 (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more Potential Energy it has because it has a greater height (h) in the formula PE = mgh.

Front

What type of energy does a roller coaster have at the top of a hill?

Back

At the top of a hill, a roller coaster has Potential Energy due to its height.

Front

What type of energy does a ball rolling down a hill have?

Back

A ball rolling down a hill has Kinetic Energy because it is in motion.
