Guys,
Physics totally fascinates me!
Sorry abt the long post,but i really need aome advice...
I really love thinking about Natural Phenomenon,building models and stuff ..!
But i really think i lack at math..i mean,most of the bio of great physicist mention ability to freely use mathematical...
Ohk,i get the see saw bit,so what you are saying is,since we know if net force on Centre of mass is sum of all other forces on the body,we get,Ma(cm)=m1a1+m2a2+...+mnan...And sort of worked back to get that relation between distances,m1r1+m2r2+...?
Cmon..How can you simply define something and just start off? :(..There must be a perfectly valid explanation for why one came up with that definition ryt?:(
Center of Mass Derivation..Doubt :(
Homework Statement
Guys,I don't seem to understand how the general equation for Center of mass was derived.I mean,yeah,i get that in a rod,or other symmetric structures,it should lie at the point of symmetry more or less,How waz the general equation...
Guys,How can i give myself a proper base for engineering?i really enjoy everything about machines,physics etc..and i love math when it can visualised...But over the last few years ,lets say,i was more or less forced to self study for my own satisfaction...Can you guys please tell me how strong...
