1) I was thinking about the definitions of KE and PE... can't the values KE and PE only ever be positive...? so
ME = KE + PE
Can total mechanical energy ever be negative? I'm thinking it cannot
2) also let's say you're in a car and you collide with another car... I'm trying to compare the impact of an inelelastic vs. elastic collision.. which would actually cause more damage to you? if the cars stick... or if they rebound?
I'm really clueless on this
