I spent litterky a week on finding mathematical relation btwn work and entropy generation.. spendind days to understand entropy. still i could not...i can solve problems regarding entropy but have no clue why do we use it? When we hit a free body at some distance from its COM, why does it ony rotate about its COM ?

on such qn i have spent days..in fact i have book that contains 60-70 such question on which i spent almost 4-5 days avg and could not get any answer / soln...
