Question

how to define newton;s first and second law of motion

Answer 1

Hi Adnan!

(1) Newton’s first law of motion (Law of inertia):

Newton's first law states that a body stays at rest if it is at rest and moves with a constant velocity if already moving, until a net force is applied to it. In other words, the state of motion of a body changes only on application of a net non-zero force.

(2) Newton’s second law of motion:

Newton’s second law of motion states that, the rate of change of momentum of a body is directly proportional to the force applied to it and takes place in the direction in which the force acts.

(3) Newton’s third law of motion:

Every action has an equal and opposite reaction.
