Question

State principle of conservation of linear momentum.illustrate by an example​

Answer 1

Answer:

• The principle of conservation of momentum states that if two objects collide, then the total momentum before and after the collision will be the same if there is no external force acting on the colliding objects.

• Conservation of linear momentum formula mathematically expresses the momentum of the system remains constant when the net external force is zero.

⇒ Initial momentum = Final momentum
