Robison) Organization: Exxon Office Systems, Princeton Lines: 12 Summary: >> Mark Callow mentioned that there is a difference between >> 'zero gravity' and 'free fall'. I give up. What is it? "Zero Gravity" refers to an ideal state in which no gravitational forces (or effectively, nearly none) act upon a body so that it can "float". In Relativity theory, "free fall" refers to the state in which an object is acted upon by gravitational forces ONLY. - Toby Robison (not Robinson!) {allegra, decvax!ittvax, fisher, princeton}!eosp1!robison
