CBSE Class 11-science Answered
vehicles stop on applying brakes. Does this violate the principle of conservation of momentum.

Expert Answer
No not at all.
This is very much in accordance with law of conservation of momentum as there is no external force acting on the system.
When we apply brakes to a vehicle, a retarding force is applied due to which it stops.
This occurs in a way such that the total loss in momentum of the vehicle is equal to gain in momentum of the brake system i.e. change in momentum of the applied force.
So, total momentum of the system remains conserved.
