Question

Explain newtons three laws in brief​

Answer 1

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

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.

Answer 2

1st law: A body at rest will remain at rest and a body in motion will remain in uniform motion unless acted upon by an unbalanced force.

2nd law: The rate of change of momentum of an object is proportional to the net force applied on the object.

3rd law: In any interaction between two bodies, the force applied by the first body on the second is equal and opposite to the force applied by the second body on the first.
