Final answer:

Newton's first law states that an object at rest remains at rest unless acted upon by an unbalanced force.


Explanation:

Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force, known as the law of inertia.

Inertia is the tendency of an object to remain at rest or remain in motion, directly related to its mass.

For an object at rest to begin moving, it requires an unbalanced force to act upon it.
