Gravity pulls objects together; the closer they are, the stronger the pull. Energy and mass are equivalent and interchangeable (E=mc²). The universe's expansion speed is linked to a galaxy's distance.

Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...

A new equation for accurate approximation of the Moody friction factor in the general gas-flow equation better approximates a wide range of Reynolds numbers than previously published equations. Other, ...
