Question

information about commonly used gadgets or devices which are based on the principles of newton' s laws of motion

Answer 1

Hey there,

NEWTON'S 1st LAW OF MOTION-A body prefers to remain in state of rest or state of motion unless and until an external force is applied to it.

EXAMPLE-
⇒A ball rolling on a friction less table would continue to roll unless an external force is applied to it.
⇒Air vehicles in space tends to move because no external force is applicable.

=======================================

NEWTON'S 2nd LAW OF MOTION-Rate of change of momentum is directly proportional to the applied force.

EXAMPLE-
⇒In cars, air begs minimize the injury or harm in case of an accident, which acts as external force.
⇒Jumping of a skateboard when a person jumps on it.
⇒Drawing back of hand to minimize an external force like a ball, a push by someone, etc.

====================================

NEWTON'S 3rd LAW OF MOTION-Every action has an equal and opposite reaction.

EXAMPLE-
⇒Recoil of gun when bullet is shot.
⇒Collision of two billiards ball. 
⇒Repulse in rocket due to back thrust.

the commonly used devices based on newton law of motion is trucks,fans.
PLEASE MARK AS BRAINLIEST IF HELPFUL!!!

Answer 2

Explanation:

Newton’s first law of motion:

Every object either remains at rest or uniform motion until and unless a force is applied on it.

Example:

Fidget spinner: The object probably will not start spinning on itself before turning but after spinning one, if there is no external force applied on it will continue to spin forever.

Newton’s second law of motion:

The acceleration is generated when the unbalanced force is applied to the mass of the object.

Example:

If the same energy is applied to push the car and the truck, the car will have more acceleration compared to the truck due to the less weight(mass).

Newton’s third law of motion:

For every action, there is an equal and opposite reaction which acts in the same momentum and opposite velocity.

Example:

All the vehicles are constructed according to the third law of motion.

Gym equipment is often based on a pulley, and when used for exercise, they use all 3rd laws of motion by newton.

Hope its help..
