gravity

 [grav´ĭ-te]
1. the phenomenon by which two bodies having mass are attracted to each other.
2. the gravitational attraction near a large body having mass, particularly near or on the surface of a planet or star.
specific gravity see specific gravity.
standard gravity (€g) the acceleration due to gravity at mean sea level, 9.80616 meters per second squared.

grav·i·ty

(grav'i-tē),
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.
[L. gravitas]

/grav·i·ty/ (grav´it-e)

2. the gravitational attraction near a large body having mass, particularly near or on the surface of a planet or star.

specific gravity  the ratio of the density of a substance to that of a reference substance at a specified temperature.
standard gravity  (g ) the acceleration due to gravity at mean sea level on earth, 9.80616 meters per second squared.

gravity

[grav′itē]
Etymology: L, gravis, heavy
the universal effect of the attraction between any body of matter and any planetary body. The force of the attraction depends on the relative masses of the bodies and on the inverse of the square of the distance between them.

grav·i·ty

(grav'i-tē)
The attraction toward the Earth that makes any mass exert downward force or have weight.
[L. gravitas]

gravity

the force by which masses are attracted to each other.

gravity

the force due to the attraction between two bodies or objects which depends on the product of their masses and inversely on the square of the distance between their centres of gravity.

gravity

weight; tendency toward the center of the earth.

gravity rail system
a rail system for moving carcasses of meat about in an abattoir. Carcasses move from station to station by gravity; suited only to slow kill rates.

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.
