Homework Help: Physics HELP distances, velocity formulas

  1. Sep 12, 2004 #1
    :cry: well i need couple equations explained to me. such as the distances formula, and the velocity which i'm currentlyusing i really didn't understand what goes where m/s^2?, s?, m? and so on :cry:

    do you mean instantaneous position/velocity/acceleration equations or average?

    Acceleration is in meters per second per second, m/s^2
    Time is in seconds, s
    Distance and Displacement are in meters, m
    Speed and velocity are in meters per second, m/s

    Are you looking at the equations of motion? Any of these ones:

    [tex]v(average) = \frac{s}{t}[/tex]

    [tex]a=\frac{v-u}{t}[/tex]

    [tex]s=ut + \frac{1}{2} a t^2[/tex]

    [tex]v^2=u^2 + 2as[/tex]

    If any of those are the equations you're having trouble with, I can help you understand how to use them.
