Question

laws of motions
and their definations
with examples

Answer 1

Answer:

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 sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma. (It is assumed here that the mass m is constant – see below.)

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.

Explanation:

Newton's third law states that there are no isolated forces. For each force that exists, one of equal magnitude and opposite direction acts against it: action and reaction. For example, a ball thrown onto the ground exerts a downward force; in response, the ground exerts an upward force on the ball and it bounces.
