Does inertia only apply to objects at rest, based on the First Law of Motion?

Newton's First Law is important because it explains the basic concept of a body in motion. The first law implies that an object does not change the state of uniform motion or its state of rest unless a force acts on them. It helps us understand why seat belts, brakes, and handrails are needed. It te

No, that's a common misconception about force in any object at rest. According to Newton's First Law, zero acceleration means zero net force. That does not mean zero force. A book on a table is at rest because two forces act on it. Gravity pulls it down. The table exerts an equal upward normal force
