Awesome. Thanks for that! I truly am rusty. However, leaving it a couple of weeks and looking at some electromag for a while made it a lot easier with fresh eyes. Your help was much appreciated!

So, plugging 2) into 1) gives: Fsm + Fem = (Mm x Ame) + (Mm x Aes) Then eliminating Fem = Mm x Ame gives Fsm = Mm x Aes If you assume Aes ≅ Ams (given A = V2/R and that Res ≅ Rem) All good? I feel like that was too easy.

Homework Statement Given if: (1) Fsm + Fem = Mm x Ams (2) Ams = Ame + Aes (3) Res ~= Rms Show that (4) Fem ~= Mm x Ame Where: 'Fsm' is the force between the sun and moon, 'Fem' the force between Earth and moon, etc. 'Mm' is the mass of the moon, 'Ams' the accelleration of the...
