when external force on a system is zero than linear momentum of system remains conserved.
because force is change in momentum per second
F = dP/dt
If F = 0
Then dP = 0
so P = constant
Hope 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 =0
hence momentum is constant in absence of external force.
