Question

Obtain information about
commonly used gadgets or devices
which are based on the principles
of Newton's laws of motion,
​

Answer 1

Answer:

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.

Answer 2

Answer:

Newton’s first law of motion: Fidget spinner

Newton’s second law of motion: air bags

Newton’s first law of motion: Rocket , All the vehicles, Gym equipment based on a pulley

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:

• 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.

• 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:

• Working Principle of Rocket.
• Recoil of a gun.
• 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.
