Simple but effective picture (just to give some feedback). Maybe give the masses labels, to go with the text, but it might only add an unnecessary layer of complexity. I mean, how many parts are there to lose track of? Femto 14:14, 16 Oct 2004 (UTC)
[edit] Gravity
If m2 is heavier than m1, shouldn't it be being pulled down by gravity? Meaning there should be a negative sign before the part of the m2 formula containing the gravity constant?
Or overall, shouldn't the first two formulas for the forces affecting m1 and m2 be switched?
[edit] Demonstration
Ok, if this is a popular demonstration then it surely isn't right to describe it as involving inelastic strings and ideal pulleys. I'll fix this if I can. Theoh 19:11, 6 January 2007 (UTC)
- It's not so much a demonstration as an ideal model. At least that's how I remember from my I took intro Physics. It's used in labs, too, actually, and the non-ideal conditions are taken into account as experimental error. --Ttownfeen 00:04, 10 January 2007 (UTC)
