The attraction toward the earth that makes any mass exert downward force or have weight. Strictly speaking, gravity is the algebraic sum of the gravitational attraction of the earth and the opposing centrifugal effect of the mass's rotation around the earth. Thus, gravitational attraction at the north and south poles is larger than at the equator. A satellite in a stable orbit has zero gravity because the centrifugal effect of orbital motion exactly balances the gravitational attraction of the earth.

Patient discussion about gravity
Q. How to Get Fit with Gravity, any experienced one here? I am planning to buy a gravity machine because some one told that it is the cheap and best machine to keep me fit. How to Get Fit with Gravity, any experienced one here?
A. it all depends on what you do with it. people buy all sort of machinery in order to help them get in shape, but most of my friends that done it have the machine standing in the garage collecting dust. so i suggest going to a gym, and create a group of friends to come along with you so you'll be more motivated.More discussions about gravity
