  2. Centrifugal force - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_force

    The centrifugal force must be included in the passenger's reference frame (in which the passenger remains at rest): it counteracts the leftward force applied to the passenger by the seat, and explains why this otherwise unbalanced force does not cause them to accelerate. [17]

  3. Spacecraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_flight_dynamics

    A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.

  4. Artificial gravity - Wikipedia

    en.wikipedia.org/wiki/Artificial_gravity

    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. In the context of a rotating space station, it is the radial force provided by the spacecraft's hull that acts as centripetal force.

  5. Non-inertial reference frame - Wikipedia

    en.wikipedia.org/wiki/Non-inertial_reference_frame

    Common examples of this include the Coriolis force and the centrifugal force. In general, the expression for any fictitious force can be derived from the acceleration of the non-inertial frame. [ 6 ] As stated by Goodman and Warner, "One might say that F = m a holds in any coordinate system provided the term 'force' is redefined to include the ...

  6. Rotating reference frame - Wikipedia

    en.wikipedia.org/wiki/Rotating_reference_frame

    Centrifugal force is one of several so-called pseudo-forces (also known as inertial forces), so named because, unlike real forces, they do not originate in interactions with other bodies situated in the environment of the particle upon which they act. Instead, centrifugal force originates in the rotation of the frame of reference within which ...

  7. Two-body problem in general relativity - Wikipedia

    His answer came in his law of universal gravitation, which states that the force between a mass M and another mass m is given by the formula =, where r is the distance between the masses and G is the gravitational constant. Given this force law and his equations of motion, Newton was able to show that two point masses attracting each other ...

  8. Gravity - Wikipedia

    en.wikipedia.org/wiki/Gravity

    Gravitation, also known as gravitational attraction, is the mutual attraction between all masses in the universe.Gravity is the gravitational attraction at the surface of a planet or other celestial body; [6] gravity may also include, in addition to gravitation, the centrifugal force resulting from the planet's rotation (see § Earth's gravity).

  9. History of centrifugal and centripetal forces - Wikipedia

    en.wikipedia.org/wiki/History_of_centrifugal_and...

    He coined the phrase "compound centrifugal force" for a term which bore a similar mathematical expression to that of centrifugal force, albeit that it was multiplied by a factor of two. [14] The force in question was perpendicular to both the velocity of an object relative to a rotating frame of reference and the axis of rotation of the frame.
