[QUOTE="kramis, post: 891082, member: 2084"] [b]Air resistance[/b] Hypersmurf gave a really nice simplified answer to your misconception Totoro ... but I wanted to throw some actual detail on it. Your height when you "fall upward" is going to be determined by your kinetic energy ... this is energy gained from movement. When you fall up all of this energy is converted to other forms. Most of it is converted to potential energy ... this is energy you have from just being "high up" without moving. However, air resistance is friction which causes some of that energy to be lost to heat ... moving through the air sucks off some of your kinetic energy. So when you finally stop moving, you wont' have as much potential energy as you had kinetic energy when you started, but you and the air will be a bit warmer. When you start falling again you start converting the potential energy back to kinetic energy. However again some of this energy is lost through your bumping into air molecules and is turned into heat. So when you finally reach the ground you won't even have as much kinetic energy as you had potential energy when you were at your high point. [/QUOTE]
