One of the general theorems of dynamics. It's the increment of momentum of the object to be tantamount to the impulse of the combined force on it which is Ft=Δvm, or the sum of all the vectors of the impulse of the external force. If the sum of the vectors of a system that is not affected by an external force or by an external force is zero, then the total momentum of the system remains unchanged, this conclusion is called the law of conservation of momentum. The law of conservation of momentum is one of the most important and universal conservation laws in Nature. It applies to both macroscopic objects and microscopic particles. It is applicable to both low speed moving objects and high speed moving objects. It is an experimental rule and can also be deduced by Newton's second law and kinematics formulas.

Momentum: ΔM = m*Δv

ΔM = Momentum change

m = Quality

Δv = speed change
