Momentum is the capacity to make other objects move in the direction of its motion. Momentum is the conserved quantity of moving. It is transferred between objects. When 2 bumper cars collide, they do not transfer force or energy. They transfer momentum.
Generally people get confused between energy and momentum. So 2 main differences:
*Energy can be stored, momentum can't be. There is potential energy but there is "no potential momentum". Energy is about doing. Momentum is about moving. Without movement, there is no momentum. A stationary object has zero momentum.
*Unlike energy, momentum is a vector quantity. Momentum has direction.
