On the trajectories of bodies in non-inertial reference frames

open access: yesVestnik Tomskogo gosudarstvennogo universiteta. Matematika i mekhanika, 2023
This paper considers a trajectory of the body moving under the influence of the force F in a non-inertial reference frame (NRF), which is "tied" to a given curve y = y(x) and is described by a natural movable basis τ-n. For this NRF, a system of linear differential equations is obtained to simulate various types of trajectories resulting from the ...

Flow past a rotating cylinder predicted by a compact Eulerian viscous vorticity method under non-inertial rotating frame

open access: yes, 2021
An Eulerian vorticity method, based on a vorticity-stream function formulation, initially developed for the 2-D viscous unsteady flow past a circular cylinder, is extended in the case of 2-D flow past a rotating cylinder in a rotational frame of ...

Unitary representations of the Galilean line group: Quantum mechanical principle of equivalence

open access: yes, 2011
We present a formalism of Galilean quantum mechanics in non-inertial reference frames and discuss its implications for the equivalence principle. This extension of quantum mechanics rests on the Galilean line group, the semidirect product of the real ...

Locally Inertial Reference Frames in Lorentzian and Riemann-Cartan Spacetimes

open access: yes, 2011
In this paper we scrutinize the concept of locally inertial reference frames (LIRF) in Lorentzian and Riemann-Cartan spacetime structures. We present rigorous mathematical definitions for those objects, something that needs preliminary a clear ...

Deduction of Lorentz Transformations from Classical Thermodynamics

open access: yesEntropy, 2015
The Lorentz transformations are obtained by assuming that the laws of classical thermodynamics are invariant under changes of inertial reference frames.

Frames of reference in spaces with affine connections and metrics

open access: yes, 1999
A generalized definition of a frame of reference in spaces with affine connections and metrics is proposed based on the set of the following differential-geometric objects: (a) a non-null (non-isotropic) vector field, (b) the orthogonal to the vector

Realization of an Inertial Reference Frame From Mark III VLBI [PDF]

open access: yesSymposium - International Astronomical Union, 1990
Over 350 000 dual frequency Mark III VLBI observations from several geodetic and astrometric observing programs have been used to realize an inertial reference frame through the positions of 325 compact extragalactic radio sources uniformly distributed over the sky with standard errors typically under 1 milliarcsecond (mas). Internal and external tests

Implications of an absolute simultaneity theory for cosmology and universe acceleration. [PDF]

open access: yesPLoS ONE, 2014
An alternate Lorentz transformation, Absolute Lorentz Transformation (ALT), has similar kinematics to special relativity yet maintains absolute simultaneity in the context of a preferred reference frame.

Electrodynamics in accelerated frames revisited

open access: yes, 2010
Maxwell's equations are formulated in arbitrary moving frames by means of tetrad fields, which are interpreted as reference frames adapted to observers in space-time.

Simple pendulum in a rotating reference frame

open access: yesRevista Brasileira de Ensino de Física
Describing the harmonic motion of a simple pendulum observed from a rotating reference frame necessitates solving the differential equations governing three-dimensional motion in a non-inertial reference frame, which can be a challenging endeavor for ...
