where ħ is the reduced Planck constant, a is the proper uniform acceleration, c is the speed of light, and k B is the Boltzmann constant. Thus, for example, a proper acceleration of 2.47 × 10 20 m⋅s −2 corresponds approximately to a temperature of 1 K. Conversely, an acceleration of 1 m⋅s −2 corresponds to a temperature of 4.06 × 10 ...
Key takeaways Acceleration clauses, a common feature in mortgage contracts, require that you pay off your entire loan balance immediately in a single lump sum. If you're unable to pay off the ...
The deceleration parameter in cosmology is a dimensionless measure of the cosmic acceleration of the expansion of space in a Friedmann–Lemaître–Robertson–Walker universe. It is defined by: q = d e f − a ¨ a a ˙ 2 {\displaystyle q\ {\stackrel {\mathrm {def} }{=}}\ -{\frac {{\ddot {a}}a}{{\dot {a}}^{2}}}} where a {\displaystyle a} is ...

Even in calculations requiring high precision, the centrifugal force is generally not explicitly included, but rather lumped in with the gravitational force: the strength and direction of the local "gravity" at any point on the Earth's surface is actually a combination of gravitational and centrifugal forces. However, the fictitious forces can ...
Different theories of dark energy suggest different values of w, with w < − 1 / 3 for cosmic acceleration (this leads to a positive value of ä in the acceleration equation above). The simplest explanation for dark energy is that it is a cosmological constant or vacuum energy; in this case w = −1.

In classical physics and special relativity, an inertial frame of reference (also called an inertial space or a Galilean reference frame) is a frame of reference in which objects exhibit inertia: they remain at rest or in uniform motion relative to the frame until acted upon by external forces.
