Artificial gravity is the varying (increase or decrease) of apparent gravity (g-force) via artificial means, particularly in space, but also on the Earth. It can be practically achieved by the use of some different forces, particularly the centrifugal force and linear acceleration (fictitious forces).
The creation of artificial gravity is considered desirable for long-term space travel or habitation, for ease of mobility, for in-space fluid management, and to avoid the adverse long-term health effects of weightlessness.

Famous quotes containing the words artificial and/or gravity:
“Description is revelation. It is not
The thing described, nor false facsimile.
It is an artificial thing that exists,
In its own seeming, plainly visible,
Yet not too closely the double of our lives,
Intenser than any actual life could be....”
—Wallace Stevens (18791955)
“Grown beyond nature now, soft food for worms,
They lift frail heads in gravity and good faith.”
—Derek Mahon (b. 1941)
