Question

9th class physics State the Newton first law of motion​

Answer 1

Newton's first law of motion states that there must be a cause—which is a net external force—for there to be any change in velocity, either a change in magnitude or direction. An object sliding across a table or floor slows down due to the net force of friction acting on the object.

Answer 2

Answer: A body in motion continues to move and a body at rest will be in rest untill and unless any external force acts on the body.
