In a straight-line motion, how are speed and velocity related?
A
Velocity is the magnitude of the speed vector, so .
B
Speed is a vector and velocity is a scalar; they differ only by units.
C
Speed is the magnitude of the velocity vector; equivalently, .
D
Speed and velocity are always identical because both include direction.
