Find equation for mass in gravityA satellite is moving in circular motion round a planet.From the physics we know that Σ F r = m a r = G M m r 2 So I wanted to find the equation for M knowing also that v = ω r = 2 π r T and a r = v 2 r Thus, m a r = G M m r 2 a r = G M r 2 v 2 r = G M r 2 ( 2 π r T ) 2 r = G M r 2 4 π 2 r 2 T 2 r = G M r 2 4 π 2 r 3 T 2 = G M r 2 4 π 2 r 5 T 2 = G M 4 π 2 r 5 G T 2 = MHowever, this is wrong! It should be: M = 4 π 2 r 3 G T 2 What was my mistake in Mathematics? Please don't migrate it to physics because my misunderstanding is on math.Note: I would be very happy if you show my mistake, instead of showing me another way to get to the equation.
