MATHEMATICAL EXPRESSION:
FROM NEWTON'S THEIR LAW,
[tex]f12 = - f21 [/tex]
F=∆p/t
[tex] \frac{m2 v2 - m2 u2}{t} = \frac{m1v1 - m1 u1}{t} \\ m1u1 + m2u2 = m1v1 + m2v2[/tex]
Conversation of momentum is a law in Newtonian physics which states that the velocity of 2 object before colliding and after colliding is the same
Newton's third law states that for a force applied by an object A on object B, object B exerts back an equal force in magnitude, but opposite in direction. This idea was used by Newton to derive the law of conservation of momentum. ... B=m_{2}(v_{2}-u_{2}) (change in momentum of particle B)
