In       both cases you have a system with some potential energy, which is used       to do work (and in which frictional forces result in that potential       energy being converted to heat as the iron mass slides).       -- jt]]              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
