4) Law
of conservation of linear momentum
​

Answer 1

→ The principle of conservation of momentum states that if two objects collide, then the total momentum before and after the collision will be the same if there is no external force acting on the colliding objects.

→ Conservation of linear momentum formula mathematically expresses the momentum of the system remains constant when the net external force is zero.

Initial momentum = Final momentum

APPLICATIONS-

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
