Answer: Inertia
Explanation:
The tendency of an object to resists change in its motion is called inertia. This implies that the body possesses zero velocity since the body is not moving. A body only accelerates or change its position only when such body is acted upon by an external agency called unbalanced force.
For example, a book placed on a table will never leave that position unless someone pick it up or such individual unknowingly shifts the book from the original place (this is the unbalanced force described above).
