    Doing some revision for a physics test here, keep getting confused with this simple bit of math
    T = 2pi √((h^2+k^2)/gh))
    What is the unit of K?
    h= m
    g= ms^-2
    t= s
    2pi = no unit

    Find an equation for k in terms of the other variables. Then remove all constants and substitute in the units. Then simplify.

    I think you can just say that if you are h^2 to k^2 then they need the same units?

    I never thought dimensional analysis would actually come in useful

    I think it's one of the most useful tools in a physicists toolbox! Get ready for lots of it at Cornell.

    I have a love/hate relationship, depends on how rigorous I'm feeling that particular day.
