The term that describes how quickly something is moving is speed. Speed is defined as the distance traveled over a certain period of time and is a scalar quantity, meaning it only has magnitude and no direction. For example, if a car travels 60 miles in one hour, it is said to have a speed of 60 miles per hour, indicating how fast it is moving regardless of its travel direction.

Acceleration measures how quickly an object's speed changes over time, making it relevant to the variation in speed rather than the speed itself. Displacement refers to the change in position of an object and is a vector quantity that includes direction. Velocity combines speed and direction, illustrating not just how fast something is moving but also in which direction it is moving.
