Newton’s First Law of Motion – Idea of Inertia

States that an object continues in its states of rest or uniform motion in a straight line unless an external force acts on it.

It is a common experience that a body at rest will remain at rest. For example, a book at rest on top of a table will remain there unless something pushes it or pulls at it. Also as was first pointed out by Galileo, the motion of a body once started, would continue along a straight line path.... View More
