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.

How does speed affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed. If the speed of an object doubles, its Kinetic Energy increases by a factor of four.

What happens to Kinetic Energy when an object slows down?

Back

As an object slows down, its Kinetic Energy decreases.

Front

Can an object have Kinetic Energy if it is not moving?

Back

No, an object must be in motion to have Kinetic Energy.

What is the relationship between Kinetic Energy and potential energy?

Back

Kinetic Energy and potential energy are forms of mechanical energy. They can convert into each other; for example, potential energy converts to Kinetic Energy when an object falls.

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a flying baseball, or a running person all demonstrate Kinetic Energy.
