  2. Artificial gravity - Wikipedia

    en.wikipedia.org/wiki/Artificial_gravity

    Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. [1] Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of ...

  3. Circular motion - Wikipedia

    en.wikipedia.org/wiki/Circular_motion

    Category. v. t. e. In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular arc. It can be uniform, with a constant rate of rotation and constant tangential speed, or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves ...

  4. Acceleration - Wikipedia

    en.wikipedia.org/wiki/Acceleration

    Acceleration is the rate of change of velocity. At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction at that point. The true acceleration at time t is found in the limit as time interval Δt → 0 of Δv/Δt.

  5. Centripetal force - Wikipedia

    en.wikipedia.org/wiki/Centripetal_force

    t. e. A centripetal force (from Latin centrum, "center" and petere, "to seek" [1]) is a force that makes a body follow a curved path. The direction of the centripetal force is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. Isaac Newton described it as "a force by ...

  6. Fictitious force - Wikipedia

    en.wikipedia.org/wiki/Fictitious_force

    t. e. A fictitious force is a force that appears to act on a mass whose motion is described using a non-inertial frame of reference, such as a linearly accelerating or rotating reference frame. [1] Fictitious forces are invoked to maintain the validity and thus use of Newton's second law of motion, in frames of reference which are not inertial. [2]

  7. Jerk (physics) - Wikipedia

    en.wikipedia.org/wiki/Jerk_(physics)

    Jerk (physics) In physics, jerk (also known as jolt) is the rate of change of an object's acceleration over time. It is a vector quantity (having both magnitude and direction). Jerk is most commonly denoted by the symbol j and expressed in m/s 3 ( SI units) or standard gravities per second ( g0 /s).

  8. Centrifugal force - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_force

    Centrifugal force is an inertial force in Newtonian mechanics (also called a "fictitious" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It is directed radially away from the axis of rotation. The magnitude of centrifugal force F on an object of mass m at the distance r from the axis of ...

  9. Rotating wheel space station - Wikipedia

    en.wikipedia.org/wiki/Rotating_wheel_space_station

    In theory, the station could be configured to simulate the gravitational acceleration of Earth (9.81 m/s 2), allowing for human long stays in space without the drawbacks of microgravity. History. Both scientists and science fiction writers have thought about the concept of a rotating wheel space station since the beginning of the 20th century.
