What does Newton's First Law of Motion state?

Newton's First Law of Motion, often referred to as the law of inertia, states that an object will remain at rest or in uniform motion in a straight line unless acted upon by a net external force. This principle highlights the concept that objects naturally resist changes in their state of motion. The statement that an object will stay at rest unless acted upon by an unbalanced force captures the essence of inertia—meaning that without an external force, a stationary object will not move, and a moving object will not change its velocity.

This law is fundamental in understanding how forces affect the motion of objects. In this context, when discussing the concept of unbalanced forces, the law emphasizes that any change in motion requires some form of external influence. This understanding serves as a foundation for exploring more complex interactions in physics, such as dynamics and the effects of various forces on motion.

The other choices describe different principles or laws in physics, but they do not accurately represent Newton's First Law. The second statement touches on constant speed and external forces, which is related but more specific in context. The third statement corresponds to Newton's Third Law of Motion, while the fourth statement defines Newton's Second Law, relating force, mass, and acceleration. Therefore, the answer accurately captures
