In the study of kinematics, 'acceleration' means any change
in the speed or direction of motion.
Speed is a measure of how fast an object is moving, while velocity includes both speed and direction. Speed is a scalar quantity, meaning it only has magnitude, while velocity is a vector quantity, which includes both magnitude and direction.
Speed and velocity both describe how fast an object is moving. The main difference is that velocity includes direction, whereas speed is just a measure of how fast something is moving regardless of direction.
Velocity is the measure of speed in a certain direction. It is a vector quantity that includes both the speed of an object and the direction in which it is moving.
Speed and velocity both measure how fast an object is moving. However, velocity also includes the direction of the movement, while speed does not.
There is no synonym to velocity. there is no directionality in velocity. speed is a measure of rotation around a center expressed in revolutions per unit of time. Velocity is a measure of distance in units of time with no direction. Vectors indicate direction.

Velocity is speed with a direction
Speed and velocity both describe how fast an object is moving. The main difference is that velocity includes direction, whereas speed is just a measure of how fast something is moving regardless of direction.
Direction. Velocity is a vector, speed is a scalar.
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
Speed and Velocity are the same thing, it is a measure of rate of change of position of an object.
Velocity is the measure of speed in a certain direction. It is a vector quantity that includes both the speed of an object and the direction in which it is moving.
http://wiki.answers.com/Q/The_difference_of_speed_and_velocity" The difference between speed and velocity is that speed is a scalar quantity(that have only magnitude) and velocity is a vector quantity(that have both magnitude and direction).
Velocity
Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
They have exactly the same size. The difference is that 'velocity' tells you which way the 'speed' is going.
A change in the position of an object is called a displacement. Velocity is the measure of the rate of change of displacement with respect to time.
