N Submit Request Answer Part C - What is causing the centripetal force? O Force of gravity O Air Resistance Tension O Force NormalArtificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the spacecraft's hull that provides the necessary centripetal force. Thus, the "gravity" force felt by an object is simply the normal force produced by the hull pushing on the object. In accordance with Newton's Second Law the value of little g created artificially is equal to the centripetal acceleration. From the point of view of habitiat, artificial gravity by rotation behaves in some ways similarly to normal gravity but with the following differences: . Centripetal Force: Unlike real gravity, which pulls towards a center of the planet, the centripetal force pushes towards the axis of rotation. For a given angular velocity the amount of artificial gravity depends linearly on the radius. With a small radius of rotation, the amount of gravity felt at one's head would be significantly different from the amount felt at one's feet. This could make movement and changing body position awkward. In accordance with the physics, slower rotations or larger rotational radii would reduce or eliminate this problem. Similarly the angular velocity of the habitat should be significantly higher than the relative velocities with which an astronaut will change position within it. Otherwise moving in the direction of the rotation will increase the felt gravity (while moving in the opposite direction will decrease it) to the point that it should cause problems. Artificial gravity space station. 1969 NASA concept. This design is flawed because the astronauts would be walking back-and-forth between gravity and weightlessness.
