What do you mean by the law of conservation of momentum?
If no force other than action and reaction forces act on two or more objects, no change takes place in their sum momentums in the opposite direction. For example, the momentum of two cars are the same before and after a collision. If F1 and F2 stand for action and reaction forces, the law of conservation of momentum states that F1 = F2.
- m1u1+m2u2=m1v1+m2v2
m1 = mass of the first object
m2 = mass of the second object
u1 = initial velocity of the first object
u2 = initial velocity of the second object
v1 = final velocity of the first object
v2 = final velocity of the second object
