Principle of Conservation of Linear Momentum
Principle of Conservation of Linear Momentum:
If there is no external forces acting on a system, the total linear momentum of the system is constant.

F1 = -F2
m1v1 +m2v2 = m1u1 +m2u2
Sum of linear momentum after collision = Sum of linear momentum before collision
The Principle of Conservation of Linear Momentum and Newton’s Third Law of Motion are consistent with each other.
