Answer 2

Hey, mate here is your answer✌✌》》

This concept is equivalent to assuming that the body is a particle with a definite mass but no size. Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
