Question

How can Newton's first law be a consequence of Newton's second law?

Answer 1

But this is just what Newtons first law states. ln other words it appears that the first law can be derived from the second and if it nothing more than a consequence of the second law , then the first law in redundan

Answer 2

Newton's 1st law of motion states that every body continues to be in its state or uniform motion in a straight line unless some external force is applied to it.

i.e. states about application of force.

Newton's 2nd law states that rate of change of momentum of a body is proportional to applied force and takes place in direction in whch force acts.

i.e. states about force that is applied on the body.

So, Newton's first law can be a consequence of Newton's second law.
