Final answer:
Newton's First Law of Motion states that objects at rest remain at rest and objects in motion stay in motion unless acted on by an unbalanced force.
Step-by-step explanation:
Newton's First Law of Motion states that an object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force.
This means that if no external force is applied, objects will maintain their current state of motion or rest. For example, a ball on the ground will stay still unless someone kicks it, and a moving car will keep moving in the same direction and speed unless a force like friction or a collision stops it.
This law is also known as the law of inertia and helps us understand the behavior of objects under various influences.
