Isaac Newton's First Law of Motion states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." What, then, happens to a body ...

Motion is movement of an object from one place to another or we can say it is the process of moving, changing place or position. Motion requires force to cause that change. The time you take to travel ...
