Difference Between Force and Momentum

Even though both these physical quantities look alike but there is a difference between force and momentum. Force is generally the external action upon a body whether it is a pulling or pushing action. Momentum on the other hand is the representation of the amount of motion within a moving body.

Difference Between Force and Momentum

The major relation would be that force results in change in momentum. According to the newton’s second law, the change of momentum of any object is also called force which is given by mass times acceleration. Momentum changes with the change in velocity whereas force changes with the change in acceleration.

Momentum depends on time and the longer a force is applied, the amount of momentum increases. Both of these quantities are vector quantities meaning they both have magnitude and direction.

Difference Between Force and Momentum

Force

Momentum

The direction depends on acceleration

The direction depends upon the direction of velocity

The increase in time decreases the amount of force provided the momentum is constant

The increase in time results in increase in momentum

A force exists for a stationary object

The momentum is zero for a stationary object

Force can be result of actually touching between objects and without physical contact also

Momentum is the result of any unbalanced force acting on a body

Force= mass* acceleration

Momentum= mass*velocity
