The concepts of momentum and the conservation of momentum are summarized below.

Momentum Summary

Momentum is the measure of the motion of a moving body. It is the result of the product of the body's mass and the velocity at which it is moving. Therefore, momentum can be defined as:

P=mv.

The conservation of momentum states that if no net external force acts upon a system, the momentum of the system remains constant. If force (F) is equal to zero, then .

The momentum before and after a collision can be calculated using the following equation.
