According to Newton's First Law, what happens to an object at rest?

According to Newton's First Law of Motion, an object at rest will remain at rest unless acted upon by an unbalanced external force. This principle, often referred to as the law of inertia, emphasizes that objects tend to maintain their current state of motion—whether at rest or in motion—unless a force causes a change.

Thus, an object that is not influenced by any external force will stay at rest indefinitely. This is a fundamental concept in physics, highlighting the importance of forces in influencing the state of motion of objects. Understanding this principle is crucial for grasping more complex concepts in physics, as it lays the groundwork for how we explore motion and forces in various contexts.
