Question

How is the first law of motion derived from the second law?

Answer 1

Answer:

Newton's first law states that a body stays at rest if it is at rest and moves with a constant velocity unit if a net force is applied on it. Newton's second law states that the net force applied on the body is equal to the rate of change in its momentum. That is, when F = 0, v = u for whatever time, t is taken.
