Eq. (26) is often called the unsteady Stokes equation, useful for describing a certain type of flows converted with sudden acceleration or deceleration, as is the case, e.g., of bubble rise or particle impaction against interfaces. On the other hand, if the characteristic time of flow varia...

We revisit the theoretical priors used for inferring Dark Energy (DE) parameters. Any DE model must have some form of a tracker mechanism such that it behaved as matter or radiation in the past. Otherwise, the model is fine-tuned. We construct a model-independent parametrization that takes th...

Acceleration remains positive until we're halfway there (then it is negative – deceleration), so the maximum velocity is: v=12atv=21at and the kinetic energy equation is the same as the previous one. Einstein's universe — arrive at the destination at full speed The relativistic rocket equ...

As is known, the environment is able to transmit energy to an element by the action of a force over a distance (mechanical work), which causes the acceleration (or deceleration) of the element; in short, a force is able to change its kinetic energy....
The Hubble function, the deceleration parameter, and the matter energy density were obtained in each case as a function of the redshift by using analytical and numeri- cal techniques. For all considered cases the Universe expe- riences an accelerating expansion, ending with a de Sitter type ...
