Question

Commonly used gadget or devices which are based on principles of Newton's laws of motion

Answer 1

That's a good and interesting question.
space craft  revolve is based on newton law of motion which states that unless an force act on a body it will continue to move or will stay at it's position. 
that's why when space craft one's set in motion will continue to move.
Also taking off of rockets are result in reaction of force applied by the exhaustion downward the surface which is based on newton's third law of motion
.
working of air bags is based on the newton's second law of motion .

Answer 2

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.
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.


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.

Third law of motion states " For every action there is equal and opposite reaction "
Example:
Working Principle of Rocket.
Recoil of a gun.
