Law of conservation of momentum states
- (a) Total momentum of two objects is unchanged or conserved by the collision
- (b) Sum of momentum of the two objects before the collision is equal to the sum of momentum after the collision provided there is no external force acting on them
- (c) Rate of change of momentum of the first object is equal to the rate of change of momentum of the second object during a collision
- (d) All the statements are true
Ans: (d) Law of conservation of momentum can be defined in any of these three ways.
