Speed and Motion

Speed and motion describe how objects move through space. Speed measures how fast an object travels over a certain distance, calculated as distance divided by time (e.g., miles per hour). Motion refers to the change in an object's position relative to its surroundings over time. An object moving continuously in a particular direction is in motion, while if it remains in the same spot, it has no motion relative to its environment. Understanding these concepts helps explain everyday activities like driving, walking, or the movement of planets. They are fundamental in analyzing how and why objects move the way they do.
