How would you describe speed?

Explanation:
Speed is how fast something is moving, the rate at which distance is covered. It’s a scalar quantity, meaning it has magnitude but no direction. For example, a car traveling 60 miles per hour has a speed of 60 mph, regardless of which way it is going. If the car changes direction but keeps the same speed, its velocity is different because velocity includes direction, while speed does not. Acceleration describes how speed (or velocity) changes over time. Force is a push or pull that can cause acceleration, and gravity is a specific force that pulls objects toward Earth. So describing speed focuses on the rate of motion itself, not on direction or causes of changing motion.
