1.	law of linear monuntum example fast plese exam are going on during collison and collision
Answer» If the net external force acting on a system of bodies is zero, then the momentum of the system remains constant. This is the basic law of conservation of linear momentum.Example: One of the applications of conservation of momentum is the launching of rockets. The rocket fuel burns are pushed the exhaust gases downwards, and due to this, the rocket gets pushed upwards. Motorboats also work on the same principle, it pushes the water backward, and gets pushed forwards in reaction to conserve momentum.
