Newton's First Law states that " every object which is at rest or uniform motion continues to be in state of res or uniform motion unless compelled to change its state by action of net force."
Example:A space craft 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 is space.
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 backwards to reduce impact of impulse force
.Working of air bags to prevent the time of injury.
Objects in our room remain as it is unless a force as on it act.
If we shake a tree, the fruits at rest will fall down.
Third law of motion states " For every action there is equal and opposite reaction "
Example:
Working Principle of Rocket.
Recoil of a gun.

There are various gadget works on the basis of law of motion.
State of rest of a toy placing in a room shows the newton first law of motion as it states that "unless a body is moved by an unbalanced force the body will remain at it's position" Moreover a spacecraft moving in the orbit around earth will remain moving in space once starts moving in orbit.
Similarly air bags of the car work on the principal of second law of motion as the breaks are applied in order to prevent the injury.
Additionally, launching of a rocket is a perfect example of the third law of motion as it states " The action and reaction are equals but opposite in direction".
Rockets on launching exerts gaseous pressure towards ground as the reaction of which the opposite force help in launching of rocket.
