Which one of the following terms is used to indicate the natural tendency of an object to remain at rest or in motion at a constant speed along a straight line? A. velocityB. inertiaC. accelerationD. equilibriumE. force

Answer:B Inertia

Explanation:

Inertia is the tendency of a body to remain at present state or remain unchanged unless a force is acted upon it.

for example, if a body is moving with linear velocity in a straight line then the inertia allows the body to move in a straight line unless a force like the friction of any other external force to stop it.

Rolling of a ball down the inclined plane continuously until friction is applied.
