Newton's First Law states that " every object which is at rest or uniform motion continues to be in a state of rest or uniform motion unless compelled to change its state by the action of net force."
Example: A spacecraft far from any source of gravity would need no thrust to keep it moving at a constant speed in a given direction.Once set in motion, it continues to move forever without propulsion since there is no friction in space.
The second law of motion " Rate of change of momentum of the body is directly proportional to the force acting on it."
Example: Fielder in a cricket match pulls his hand back to reduce the impact of impulse force.Working of airbags to prevent the time of injury.
Third law of motion states " For every action there is equal and opposite reaction "
Example: Working Principle of Rocket.The recoil of a gun.

Explanation:
For every action, there is an equal and opposite reaction which acts in the same momentum and opposite velocity. Example: All the vehicles are constructed according to the third law of motion. Gym equipment is often based on a pulley, and when used for exercise, they use all 3rd laws of motion by newton
