RE: Does Kinetic Energy = Penetration?
OK, this is more of a question than difference of opinion. Wouldn't the pine needle/2 by 4 in a tornado example be skewed? Like Greg said earlier and arrow begins losing energy immediately after it leaves the string. The pine needle and 2 by 4 would not be losing energy because there is a constant force propelling it (the dang tornado). If that force were to suddenly cease, which do you think would travel farther?
