Conservation means Constant....Momentum is a physical quantity which is conserved if there is no external force acting on a body...
Momentum is denoted by letter p ,
It is measured by the calculating the product of mass and velocity...so p = m × v
Initial momentum , p1 = m × u ( u = initial velocity )
Final momentum , p2 = m × v ( v = final velocity )
Change in momentum = p2 - p1 = mv - mu
Proof
=====
F = Rate of change in momentum
= Change in momentum / change in time
F = ( mv - mu ) / t ---( i )
As there no external force on a body , then F = 0
Equation ( i ) becomes
0 = ( mv - mu ) / t
=> ( mv - mu ) / t = 0
=> mv - mu = 0
=> mv = mu
=> p2 = p1
=> Final momentum = Initial momemtum
=> Momemtum is conserved
