## 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.
[L. gravitas, weight]

## 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.

It is for this reason that unifying the force of gravity and the strong force with the electro-weak interactions is so challenging.
In orbit, aboard the international space station for example, gravity is still present, but because an orbiting body is effectively in 'free-fall', the centrifugal force on the astronauts (because they're going around the planet so quickly), is large enough to balance out the force of gravity.
If you squeeze the bottle enough, the buoyant force becomes less than the force of gravity, and the diver is pulled down.

This creates a pressure 4,000 times the force of gravity, which squeezes the juice out of the apple pieces.
It is then clear why the force of gravity is only an attraction, because repulsion would cause the string to bend.
The housings structural requirements include impact resistance to accelerations greater than 230 times the force of gravity.

They also took corners at four times the force of gravity to take the world championship and cup titles.
But beyond that, the need for quad and calf strength, upper-body coordination, balance, and sensory awareness both of others and of abrupt terrain changes on the mountain makes skiing an exceedingly challenging sport to perform safely at the speeds it insists upon by sheer force of gravity.
This no-plug performance is derived from a maximization of the force of gravity by a computer-designed trapway and flapperless valve, plus a sipbonic washdown system that directs all the water through the rim to keep the bowl clean.
