Newton first law of motion = an object will continue to remain in its state of rest or in a uniform motion along the straight line or path unless an external force acts on it.
common examples - a person standing in a moving us falls forward if the driver applies brakes suddenly.
the carpet is beaten with a stick to remove the dust particles.
___________________________________________________________
Newton second law of motion = The rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts.
force ∝ change in momentum/time taken
example - A CRICKET PLAYER MOVES HIS HANDS BACKWARD WHILE CATCHING A CRICKET BALL.

Newton third law of motion- action is equal and opposite reaction
example- 1. collision of two persons
2. recoil of gun
3. rocket propulsion
