Velocity
A Vector is the measurement of velocity and direction.
velocity is the name given to speed in a specific direction.
The word is "stationary" for not moving, and "constant velocity" for moving at a constant speed in the same direction.
Another word for "in the direction of" is "toward."
Airspeed
The word speed is distance per unit of time. It is frequently used as a substitute for velocity, and it is in more common usage. But there is a difference between speed and velocity. Velocity has a direction vector associated with it. It's speed + direction. That's usually not a big deal when talking about "regular" stuff, but don't tell a physics teacher that.
A measure in one direction is called a vector. Some specific vectors are length, width, height and radius.

Rate is another word for speed. It is the speed.
another word for fast is speed
The word that means distance traveled per unit time is "speed." Speed is a measure of how quickly an object moves from one place to another, expressed as the distance traveled per unit of time.
Measure of averages.
