What distinction does the passage make between speed and velocity?

The distinction made in the passage highlights the fundamental difference between speed and velocity in terms of their mathematical and conceptual definitions. Speed is classified as a scalar quantity, meaning it is described solely by its magnitude, which represents how fast an object is moving regardless of its direction. Conversely, velocity is a vector quantity, which means it incorporates both magnitude and direction. This distinction is crucial in physics, as it affects how these measurements are applied in analyses of motion.

While certain answers might suggest speed and velocity are the same or interchangeable, the accurate recognition of speed as a scalar and velocity as a vector underscores their differing characteristics and implications in understanding motion.
