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 speed.

What is the formula for calculating Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is the mass and v is the velocity of the object.

How does mass affect Kinetic Energy?

Back

The greater the mass of an object, the more Kinetic Energy it has at the same speed.

Front

How does speed affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed; if the speed doubles, the Kinetic Energy increases by four times.

Front

What happens to Kinetic Energy when an object slows down?

Back

When an object slows down, its Kinetic Energy decreases.

What is the relationship between Kinetic Energy and potential energy?

Back

Kinetic Energy and potential energy are forms of mechanical energy; as potential energy increases, Kinetic Energy may decrease, and vice versa.

What is the effect of friction on Kinetic Energy?

Back

Friction can reduce Kinetic Energy by converting it into thermal energy (heat).
