Obtain information about commonly used gadgets or devices which are based on the principles of Newton' laws of motion.
First Law of Motion
Every object which is at rest or uniform motion continues to be in rest or uniform motion unless compelled to change its state by the action of net force.
Example: A space craft in space
Second Law of Motion
The rate of change of momentum of a body is directly proportional to the force acting on it.
Example: Air bags, shaking of tree and fruits fall, the fielder in match pulls his hand backwards to reduce impact.
Third Law of Motion
For every action, there is an equal and opposite reaction.
Example: Principle of rocket, recoil of gun.
