Distinguish between the terms speed and velocity.
(N/A) Speed is defined as the rate of change of distance with respect to time. It is a scalar quantity,meaning it has only magnitude and no direction. It is always positive.
Velocity is defined as the rate of change of displacement with respect to time. It is a vector quantity,meaning it has both magnitude and direction. It can be positive,negative,or zero depending on the direction of motion.
