Question

what is Newton first law second law and third law of motion

Answer 1

$hey \: here \: your \: answer$




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 mof 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.

Answer 2

NEWTON'S FIRST LAW OF MOTION: - states that if a body is in rest it will remain in rest and if the body is in motion it will remain in motion until an external force is applied to it.

NEWTON'S SECOND LAW OF MOTION: -states that rate of change of momentum is directly proportional to the force applied on a body and the change in momentum takes place in the direction of the force applied.

NEWTON'S THIRD LAW OF MOTION: -States that every action has equal and opposite reaction.
