Velocity, speed, acceleration and ?

  1. Sep 28, 2009 #1
    a very simple question: I know the difference between velocity and speed. I would like to know if there is an analogous for the word acceleration.

    thank you for your attention!

    A simple question, specially not being mother tongue English. What is the real difference between "velocity" and "speed"???

    Vector (velocity) vs scalar (speed).

    And, to be of even better help than Borek:

    In Norwegian, velocity is "hastighet" and speed is "fart" (for those of abstruser educational level, celerity is "hurtighet")

    Are you asking if there is an analogous word or an analogous concept?
