Ans. No, Newton's laws of motion are not limited to Earth. They are applicable in any inertial frame of reference, including the microgravity environment of space. However, in extreme conditions such as near the speed of light or in the presence of strong gravitational forces, Einstein's theory of relativity becomes necessary to accurately describe motion. Nonetheless, Newton's laws of motion remain highly applicable for most everyday scenarios and are still taught as a fundamental framework for understanding motion.
