This reaction force is sometimes described as a centrifugal inertial reaction, [44] [45] that is, a force that is centrifugally directed, which is a reactive force equal and opposite to the centripetal force that is curving the path of the mass. The concept of the reactive centrifugal force is sometimes used in mechanics and engineering.
Occupants of the station would experience centrifugal acceleration, according to the following equation: [4] a = − ω 2 r {\displaystyle a=-\omega ^{2}r} where ω {\displaystyle \omega } is the angular velocity of the station, r {\displaystyle r} is its radius, and a {\displaystyle a} is linear acceleration at any point along its perimeter.
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. ... The so-called 'centrifugal force', ...
During circular motion the acceleration is the product of the radius and the square of the angular velocity, and the acceleration relative to "g" is traditionally named "relative centrifugal force" (RCF). The acceleration is measured in multiples of "g" (or × "g"), the standard acceleration due to gravity at the Earth's surface, a ...
where = is the apparent acceleration in the rotating reference frame, the term () represents centrifugal acceleration, and the term is the Coriolis acceleration. The last term, − d Ω d t × r {\displaystyle -{\tfrac {\mathrm {d} {\boldsymbol {\Omega }}}{\mathrm {d} t}}\times \mathbf {r} } , is the Euler acceleration and is zero in uniformly ...
Centrifugal acceleration of astroparticles to relativistic energies might take place in rotating astrophysical objects (see also Fermi acceleration). It is strongly believed that active galactic nuclei and pulsars have rotating magnetospheres , therefore, they potentially can drive charged particles to high and ultra-high energies.
The applied acceleration a can be either the gravitational acceleration g, or more commonly the centrifugal acceleration ω 2 r. In the latter case, ω is the angular velocity of the rotor and r is the distance of a particle to the rotor axis ( radius ).
The Eötvös effect is the change in measured Earth's gravity caused by the change in centrifugal acceleration resulting from eastbound or westbound velocity.When moving eastbound, the object's angular velocity is increased (in addition to Earth's rotation), and thus the centrifugal force also increases, causing a perceived reduction in gravitational force.
