Question

Show that 1st law of newton can be derived from 2nd law of motion

Answer 1

1st law of Newton is A body continues to be in its state of rest of of uniform motion along straight line unless some force is acted on that object.

2nd law of Newton is force is directly proportional to rate of change of linear momentum.

1st law of newton is derived from 2nd law of Newton.
acceleration of object is directly proportional to net force acting on object and inversely proportional to
object's mass
