Question

Derive and explain the linear momentum by third law of motion ?

Answer 1

According to third law of motion to every action there is an equal and opposite reaction....e.g if you push against a wall the wall pushes back against you with the same amount of force.

Answer 2

the Newton's third law of motion = Every action force has an equal and opposite reaction force which has acts simultaneously.
Due to go in opposite direction they make a linear momentum.
ex.rocket launching.
