Question

Derive the principal of conservation of linear momentum for colliding bodies using Newton's third law of motion
​

Answer 1

Answer:

Derivation of Conservation of Momentum

Applying Newton's third law, these two impulsive forces are equal and opposite i.e. If the time of contact is t, the impulse of the force F21 is equal to the change in momentum of the first object. ... This relation suggests that momentum is conserved during the collision.
