The conservation of momentum is a fundamental law of physics which states that the momentum of a system is constant if there are no external forces acting on the system. It is embodied in Newtons first law (the law of inertia).
In Newtonian mechanics, linear momentum, translational momentum, or simply momentum (plural: momenta) is the product of the mass and velocity of an object. It is a three-dimensional vector quantity, possessing both magnitude and direction. If m is an objects mass and v is the velocity (also a vector), then the momentum is given by:
p = m * v
If the velocities of the masses are u_1 and u_2 before the interaction, and afterwards they are v_1 and v_2, then:
m1u1 + m2u2 = m1v1 + m2v2
Where:
m1: object mass 1, in Kg
u1: object 1 initial velocity, in m/s
v1: object 1 final velocity, in m/s
m2: object mass 2, in Kg
u2: object 2 initial velocity, in m/s
v2: object 2 final velocity, in m/s
