Question

Obtain information about commonly used gadgets or devices which are based on the principle of Newton law of motion.

Answer 1

- Hint: Sir Isaac Newton discovers that Newton’s laws of motion has three laws; Newton's first law of motion stated that an object will not change its motion until and unless a force acts on it. Newton’s second law of motion is defined as the force on an object is equal to its mass times its acceleration. Newton’s third law of motion is defined as that for every action, there is an equal and opposite reaction. Sometimes we refer newton’s third law of motion as law loosely as action reaction

Complete step-by-step solution -
The commonly used gadget or devices which are based on the principle of newton law of motion are:
The wheels and levers follow Newton's third law of motion as reaction force is the driving mechanism for these two gadgets.
The Elevators or lifts follow Newton's second law of motion according to which the tension in rope is determined to limit the acceleration.
The Gym equipment is mostly pulley based, so they use Newton's third law of motion when used for workout.
The Vehicles are designed by considering all Newton’s laws of motion.

Note: There is a Newton fourth law which is known as Newton’s gravitational law which states that when the two particles of M and m are mutually attracted with an equal and opposite forces i-e F and –F accordingly to the following relationship:
$\vec F = G\dfrac{{Mm}}{{{r^{^2}}}}$ Where r is the distance between the two particles and G is the universal constant of gravitation.
