The tendency for an object in motion to remain in motion is called

The correct answer is "inertia".

Explanation:

Inertia: It is the state of the object which resists any change in it.

Newton's first law is also called "Law of inertia".

If the object is travelling at constant velocity then it will remain travel at the constant velocity or if it is at rest then it will remain in resting position provided that it is acted upon by an external force.

If the external force is applied to an object then, the state of the object can be changed. Otherwise, it will remain in its state.

Therefore, the tendency for an object i motion to remain in motion is called inertia.
