SUMMARY
Newton's laws of motion, specifically the first law, apply exclusively in inertial reference frames, which are defined as frames moving at constant velocity. In contrast, non-inertial reference frames, such as one experiencing acceleration, do not adhere to this law. Concrete examples include tossing a ball in space (inertial frame) versus tossing a ball on Earth (non-inertial frame), where the ball's trajectory curves due to the Earth's acceleration. A pool table serves as a practical example of an inertial frame in the xy plane, where a ball moves straight until affected by friction.
