grav·i·ta·tion

(grav'i-tā'shŭn),
The force of attraction between any two bodies in the universe, varying directly as the product of their masses and inversely as the square of the distance between their centers; expressed as F = Gm1m2l -2, where G (newtonian constant of gravitation) = 6.67259 × 10-11 m3 kg-1 s-2, m1 and m2 are the masses (in kg) of the two bodies, and l is the distance separating them in meters.

gravitation

(grăv″ĭ-tā′shŭn) [L. gravitas, weight]
The force and movement tending to draw every particle of matter together, esp. the attraction of the earth for bodies at a distance from its center.

All attempts to-date to integrate the mathematics of the large bodies and that of the quantum particles have broken down as there is no way yet of integrating the force of gravity with the other electromagnetic forces, weak and strong.
Dr Hill added: "Crucially, as far as living organisms are concerned, the levitation force balances the force of gravity right down to the molecular level.
In contrast, a centrifugal separator generally applies a force that is 5,000 times greater than the force of gravity to the process fluid to increase separation efficiency.
But some versions of string theory allow larger extra dimensions, detectable by measuring the force of gravity at small distances or from the results of atom-smasher experiments or astrophysical observations (SN: 2/19/2000, p.

Before her once-in a-lifetime takeoff, she had never been in a airplane, let alone travel at the speed of sound and experience more than seven times the force of gravity. College student publication advisor Christina Drain accompanied her prize student out to Pensacola Naval Air Station to document the event.
In this position, the force of gravity pulls the surrounding tissue away from the hip joint and enables the surgeon to more easily access the deep recesses of the pelvis.
Normally, the force of buoyancy is greater than the force of gravity, so the diver floats.
Finally, the team pushed the composite section well beyond ultimate load to a destruct-condition maneuver beyond two and a half times the force of gravity.
