Distinguished speed and velocity.
Speed can be defined as the time rate in which an object or body is moving. The direction of the movement is not stated, and the speed of an object can never be zero. Speed is considered to be scalar quantitiy.
Velocity, on the other hand is the rate in which an object or body is moving along with a direction of its movement. The velocity of an object can either be positive, negative or zero. Positive values often mean that the movement is going up or going to the right, while negative value often means movement to the left or going down. Thus, velocity is considered to be a vector quantity.
