Question

what is newton law of motion

Answer 1

Newton 1 law

It states that the body at rest will remain at rest or a body at motion will remain at motion unless some external force applied on it.


Newton 2 law

The force applied on a body is directly proportional to product of mass and acceleration produced by that body.
I.e. Force × mass × acceleration.

Explanation: Let us consider a body having
mass = m
acceleration=a
force=f
From statement: f×m×a
f=kma ( where k is constant and is known as Newton's constant )

In S.I k = 1
f =1 ( ma )
F = ma



Newton 3 law


To every action , there is equal and opposite reaction .

Answer 2

For motion, scientist Newton gave some laws which is called Newton's law of motion.

1st Law
Newton's first law states that every object will remain at rest are in uniform motion in a straight line unless compelled to change its state by the action of an internal force.



2nd law
the second law states that the acceleration of an object is depend upon two variables- the net force acting upon the object and mass of the object.


3rd Law
The third law states that all force between two object exist in equal magnitude and opposite direction.
