In one-dimensional motion, which statement correctly distinguishes speed from velocity?
A
Speed is a scalar that depends only on the magnitude of motion, while velocity is a vector that includes both magnitude and direction.
B
Speed and velocity are both vectors because they always require a direction.
C
Velocity is a scalar equal to the total distance traveled divided by time, while speed is displacement divided by time.
D
Speed can be negative when moving in the negative direction, while velocity is always nonnegative.
