what is law of newton​

Answer 1

QUESTION -

what is law of newton?

ANSWER -

Newtons law of motion :a body at rest will remain at rest or a body in motion will continue in motion until an external force applied on it.

DERIVATION OF NEWTON'S 1ST LAW

Where, F is the force applied, m is the mass of the body and a is the acceleration of the body.

So,

In absence of a force,

F = 0

=> ma = 0

=> a = 0

Since, m cannot be zero for a body.

Zero acceleration means, body at rest will remain at rest and a body in uniform motion will continue its uniform motion. Which is Newton’s 1 st law of motion.

Answer 2

Answer:

Newton’s First Law

Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.

Newton’s Second Law

Newton’s second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time.

Newton’s Third Law

Newton’s Third Law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A.
