Answer 1

Using newton disc light is produced

Gravitational force, Frictional force are working on based on newton law of motion

Answer 2

• Newton’s 1st 'Law of Motion': "an object in state of motion will remain in the state and an 'object' will remain at rest".

The best example of this "law of motion" is a vehicle that is driven. When a vehicle is driven, it remains in state of motion till it is brought to rest where it continues to be at 'rest' till started again.

• Newton’s 2nd 'Law of Motion': "the rate of change of momentum equals the force acting on a body".

An example is an air bag that is used in vehicles for safety.  

• Newton’s 3rd 'Law of Motion': “for every action,there is an equal and opposite reaction”.

An example is a rocket. When a rocket is to be launched, it exerts pressure on the ground as a reaction of which an opposite force helps to launch the rocket.
