ok, if angual velocity ω = linear velocity v / radius r

therefore ω=v/r

but what if i have ω^2 ( to the power of 2 )

does ω^2=v^2/r^2

or does it eqaul ω^2=(v/r)^2

many thanks, this is really bugging me and preventing me solve a problem since im not in class

it's same. moreover, if you are getting confused check it dimensionally.

Also this has nothing to do with "Linear and Abstract Algebra" so I am moving it to "General Math".
