equation for the law of conservation of momentum. The law of conservation of momentum says that the momentum before an event must be the same as the amount after due to its constant conservation. M V mv 0 or M V -m v Hence.
Also known as the principle of conservation of momentum As per Newtons 2nd Law of motion force F pt. V1 and v2 are the final velocities of the bodies. If there is no force acting on the particle then since dp dt 0 p must be constant or conserved.
It is an element of the law of inertia.
Therefore above is the equation of law of conservation of momentum where m_1u_1m_2u_2 is the representation of total momentum of particles A and B before the collision and m_1v_1m_2v_2 is the representation of total momentum of particles A and B after the collision. Then the components of momentum along each direction are conservedFor example suppose two colliding bodies have momenta and before collision and momenta and after. Ie F dp dt.
