Artificial gravity

Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. Artificial gravity, or rotational gravity, is thus the appearance of a ce
Gemini 11 tethered in 1966 the GATV-5006 Agena target vehicle performing various tests including a first artificial gravity test in a microgravity environment.
Artificial gravity space station. 1969 NASA concept. A drawback is that the astronauts would be moving between higher gravity near the ends and lower gravity near the center.
Artificial gravity has been suggested for interplanetary journeys to Mars

Centrifugal force

In Newtonian mechanics, a centrifugal force is a kind of fictitious force that appears to act on all objects when viewed in a rotating frame of reference. It appears to be directed perpendicularly fro
Riders on a swing carousel interpret the cessation of upward motion as a balancing of the force of gravity, the force of the tension of the chains, and a centrifugal force pushing them away from the center of rotation. A stationary observer on the ground observes uniform circular motion, which requires a net centripetal force that is the combination of the force of gravity and the force of the tension of the chains.
The interface of two immiscible liquids rotating around a vertical axis is an upward-opening circular paraboloid.
