## 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.

Possible relationship between thinner Cenozoic sediments, decrease in the Earth gravitational attraction and elevation of benchmarks south of Byczen Depression was noticed near Sosnowa.
If the gravitational attraction between two objects, each of known mass, at a known distance from each other, could be measured, that would be measured, that would allow the gravitational constant to be calculated and, from that, the mass of the Earth.
2~ = mass of object 2 r = distance between the two objects x = gravitational attraction
This repulsion might provide insight into dark energy, the mysterious component of the universe that counteracts gravitational attraction and causes the cosmos to expand at an accelerating rate.
Among other things, they found that when photons move in parallel beams, there is no gravitational attraction between them.
In particular, Euclid will address one of the most important questions in modern cosmology: why is the universe expanding at an accelerating rate today, rather than slowing down due to the gravitational attraction of all the matter in it?
The earth/moon system is kept in orbit around the sun by the gravitational attraction between the sun and the earth/moon system and will remain so for the life of the sun, at the same average orbital velocity, unless impacted by a planet sized interstellar body.
The gravitational attraction between the two bodies would give the asteroid the smallest of nudges into a safe orbit.
Are there theories that provide a mechanism for particle creation, the increase in mass over time of these particles, a decrease in gravitational attraction between them, and the increase in the Earth's rotation rate?
The science is complicated, but it has to do with how the gravitational attraction of the sun and moon effects on our planet.
In other words: F = gmm'/d2 where g is the gravitational constant, m and m' are the masses of the Earth and the Moon, d is the distance between their centers, and F is the force of gravitational attraction between them.
The aim of EPF |1922~ was to inquire into the proportionality between inertia and gravitation using the torsion balance to establish that gravitational attraction was independent of the nature of bodies.
