Basic Concept of Momentum 

It determins the quantity of motion in a body. It is defined as the "mass of the body multiplied by its velocity". It is measured in kilogram metre per second (kgm/s) or newton second (Ns). Momentum = mass X velocity P = m v As velocity is a vector quantity, so momentum is a vector quantity too. We must give a direction when we talk about momentum. Momentum is very useful when we meet problems involving collisions or explosions. There is always as much momentum after a collision as there is before it (Principle of conservation of momentum).
