In kinematics, which statement correctly describes how speed and velocity differ?
A
Speed and velocity are the same quantity; the terms are interchangeable in physics.
B
Speed includes direction, while velocity is only the magnitude of motion.
C
Speed can be negative, while velocity is always nonnegative.
D
Speed is a scalar (magnitude only), while velocity is a vector with both magnitude and direction.
