obtain information about commonly used gadgets or devices which are based on the principles of Newton's law of motion
Answers
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.
