LAW OF CONSERVATION OF MOMENTUM
It states that in the absence of external unbalanced force , the total momentum of a system of a object remains unchanged.
LAW OF MOTION
According to Newton's second law of motion
force= mass of B × acceleration.
F1 = m2 (v2-u2)÷t
F2 = m1 ( v1-u1)÷t
According to Newton's third law of motion
F1= -F2
m2 (v2 - u2)÷t = - m1
(v1-u1)÷t
-
= m1u1 +m2u2 = m1v1+m2v2
The total momentum before collision is equal to the total momentum after collision.
