Answer 1

1. Newton first law of motion says that unless an external force is applied the body will continue to be remain in state of rest or in uniform motion is moving with a uniform velocity
e.g. ball kept AT Road doesn't move on its own because no force is applied on it
and
a moving ball will not understand the force of friction acts on it moving wall it stopped because force of friction acts on the Purchase there is no force of friction than the ball will continue to roll on ever and ever...

Answer 2

Newton's laws of motion are threephysical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. More precisely, the first law defines the force qualitatively, the second law offers a quantitative measure of the force, and the third asserts that a single isolated force doesn't exist. These three laws have been expressed in several ways, over nearly three centuries,[1] and can be summarised as follows:

First law:In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.

Second law:In an inertial frame of reference, the vector sumof the forces F on an object is equal to the mass m of that object multiplied by theacceleration a of the object: F = ma. (It is assumed here that the mass m is constant – seebelow.

Third law:When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
