Potential or Kinetic 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 the speed at which it is moving.

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 energy.

Front

Example of Kinetic Energy:

Back

A moving skateboard is an example of Kinetic Energy because it is in motion.

Front

Example of Potential Energy:

Back

A glass of milk sitting on a table is an example of Potential Energy because it is at rest and has the potential to fall.

Front

What type of energy does a dry cell of a battery represent?

Back

A dry cell of a battery represents Potential Energy because it stores energy that can be used to power devices.

Front

What type of energy does a running boy represent?

Back

A running boy represents Kinetic Energy because he is in motion.

Front

What type of energy is stored in a stretched rubber band?

Back

A stretched rubber band has Potential Energy because it is stored energy that can be released when the band is let go.

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with mass; if two objects are moving at the same speed, the one with greater mass will have more Kinetic Energy.

Front

How does speed affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed; if an object's speed doubles, its Kinetic Energy increases by four times.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object possesses due to its height above the ground. The higher the object, the more Potential Energy it has.
