A body of mass us m is moving with velocity u, after collinding with a wall it retunes back with velocity u. How much is the change in the momentum of the body?

Change is zero because the velocity of ball after colliding remains same.

Change in momentum =final momentum -initial momentum

Let P be change in momentum and p2 ,p1 be initial and final momentum

P=p2-p1

=mu-mu. (p=mass×velocity)

=0

This shows that momentum is constant throughout the motion or if you could understand it's a constant vector.

In accordance with the law of conservation of momentum the momentum remains unchanged as in the absence of external force.
