Question

State law of conservation of momentum. How can it be deduced using Newton ' s third law?

Answer 1

Answer:

The rate of change of velocity is directly proportional to impressed force

Answer 2

Answer:

Law of Conservation of Linear Momentum states that if no external force is acting on a body, the linear momentum of that body remains conserved.

When a bullet is fired from a gun, the bullet acquires a forward momentum(mv) and the gun acquires a backward momentum(MV).

Using Law of Conservation of Momentum,

            Total momentum before firing=Total momentum after firing

                                                              0=mv+MV
