What was Newton's First Law?

Objects don't ever move actually.

Inertia. An object in motion will stay in motion, unless acted on by an unbalanced force; same with resting.

F=ma, the more mass, the more force is exerted.

Every action has an equal and opposite reaction.

The correct answer is: Objects at rest stay at rest, and objects in motion stay in motion unless acted upon by an external force.
