first lesson in new physics class. apparently they're ahead of ours, but i'm not quite sure if that's accurate. if they are, it doesn't seem like much of a gap, nonetheless i'm gonna have to look it up.
so we combined and discussed two formulas today..
F = (mv^2)/r [centripetal force]
and
F = G (m1m2)/d^2 [gravity between two masses]
to understand motion of satellites.
just to keep in mind, G = 6.67x10^-11, radius of earth is approx 6400km again in case i forget, and earth's mass is equal to 6x10^24kg
