In the context of vectors, scalars, and displacement, how do speed and velocity differ?
A
Speed is a vector that includes direction, while velocity is a scalar that has no direction.
B
Speed is a scalar that describes how fast something moves, while velocity is a vector that includes both speed and direction.
C
Speed and velocity are identical quantities as long as the motion is changing direction.
D
Speed measures displacement per unit time, while velocity measures total distance traveled per unit time.
