According to Newton's First Law of Motion, which statement is true?

Newton's First Law of Motion, often stated as the principle of inertia, indicates that an object will maintain its state of rest or uniform motion in a straight line unless acted upon by a net external force. This principle emphasizes that both stationary bodies and moving bodies will not change their state of motion unless an external force disrupts that state. Therefore, the statement regarding a body at rest remaining at rest is a valid simplification of this law, as it ensures understanding that an object will stay still unless influenced by an outside force.

The first choice about a body in motion remaining in motion accurately conveys another aspect of the law. The third statement is misleading, as it oversimplifies how objects behave under force. The fourth statement incorrectly relates force, velocity, and the law, as it reflects principles from Newton's Second Law of Motion instead, which ties force and acceleration together rather than velocity directly.
