Is the expression Vector Velocity correct or not?

Question

As I know, velocity is vector, but in English, can I say "at vector velocity"? What's the correct expression?

Answer 1

The word velocity means: "vector speed"

i.e: a speed value and direction

Examples:

speed =  50 mi/hr

velocity = 50 mi/hr east

For social purposes, most people will understand.

But your physics teacher might exclaim!

Velocity already means vector, don't say "vector vector speed"

Answer 2

In most articles in English I read, the term Velocity Vector is used,e.g http://www.ac.wwu.edu/~vawter/PhysicsNet...

In a few cases the authors do write Vector Velocity, e.g. http://farside.ph.utexas.edu/teaching/30...

Answer 3

a vector quantity has  both magnitude and direction

so saying velocity there is no need for saying it is a vector since we already know it is a vector

so just say velocity
