The immutability of these fundamental constants is an important cornerstone of the laws of physics as currently known; the postulate of the time-independence of physical laws is tied to that of the conservation of energy (Noether's theorem), so that the discovery of any variation would imply the discovery of a previously unknown law of force.

This is a categorized list of physics mnemonics. Mechanics. Work: formula "Lots of Work makes me Mad!": Work = Mad: M=Mass a=acceleration d=distance [1] ...
8.854 187 8188 (14) × 10 −12 F⋅m −1 ... and is strongly dependent on how those units are defined. For example, the atomic mass constant is exactly known when ...
Standard atmospheric pressure for Earth sea level (14.7 psi) [34] 150 to > 550 kPa: 25 to > 80 psi Impact pressure of a fist punch (approximate) [citation needed] [56] +180 to +250 kPa +26 to +36 psi Air pressure in an automobile tire relative to atmosphere (gauge pressure) [citation needed] +210 to +900 kPa +30 to +130 psi
Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the ...
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
Advanced Placement (AP) Physics B was a physics course administered by the College Board as part of its Advanced Placement program. It was equivalent to a year-long introductory university course covering Newtonian mechanics , electromagnetism , fluid mechanics , thermal physics , waves , optics , and modern physics .
In current particle physics, the differences between some parameters are much larger than this, so the question is even more noteworthy. One answer given by philosophers is the anthropic principle. If the universe came to exist by chance, and perhaps vast numbers of other universes exist or have existed, then life capable of physics experiments ...
