physics HELP distances, velocity formulas

[elyrly]

: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:

[Darien]

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

: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:

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:

v(average) = \frac{s}{t}

a=\frac{v-u}{t}

s=ut + \frac{1}{2} a t^2

v^2=u^2 + 2as

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