Question

What distinguishes speed from velocity?

Answer 1

Speed is a scalar quantity that refers to "how fast an object is moving." It does not take into account the direction of motion. On the other hand, velocity is a vector quantity that refers to "the rate at which an object changes its position." It includes both speed and direction. Therefore, while speed only provides information about how fast an object is moving, velocity gives additional information about the object's direction of motion.
