```							when external force on a system is zero than linear momentum of system remains conserved.because force is change in momentum per secondF = dP/dtIf F = 0Then dP = 0so P = constantHope it clears.

```							F=m.a ( Here F is only stands for external force)F=m.(v-u)/t   if v=u then F=0 & if v=u then momentum, pi=mu ,pf=mv is also equal.change in momentum= pf – ​pi =0hence momentum is constant in absence of external force.
