Question

Obtain information about commonly used gadgets or device which are based on the principes of newton's laws of motion

Answer 1

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 spacecraft moving in the orbit around earth will remain moving in space once starts moving in orbit.

Newton's second law" 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.

Newton's third law of motion states " For every action there is equal and opposite reaction "

Example:

Working Principle of Rocket.

Recoil of a gun
