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 a change in momentum. According to the second law of motion, the change of momentum of an object 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.

The longer a force is applied, the larger the momentum is. 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 the velocity
The increase in time decreases the amount of force provided the momentum is constant The increase in time results in an increase in momentum
A force exists for a stationary object The momentum is zero for a stationary object
Force can be a result of actually touching between objects and without physical contact also Momentum is the result of an unbalanced force acting on a body
Force= mass* acceleration Momentum= mass*velocity
