What is the best explanation of motion?

Motion is the change in position of an object over time relative to a reference point. It can be described in terms of speed (how fast something moves), velocity (speed with direction), and acceleration (the rate of change of velocity). The laws of physics, particularly Newton's laws of motion, provide a framework to understand and predict the behavior of moving objects. Ultimately, motion is a fundamental aspect of the physical world, influencing everything from everyday activities to complex phenomena in the universe.
