Rewriting General Gravitation

Rewriting General Gravitation

General gravitation was first formulated by Newton as

F = GM1M2/r2

It can be rewritten, using area A = 4πr2 and force F = Ma, as

a = 4πGdM/dA


It can be rewritten in turn, using acceleration a = αr and density ρ = dM/dV and volume V = 8πr3, as

8πGρ = α

Which shows density as equivalent to angular acceleration, and is a law of general gravitation.

    since the inceptions of the science in better and smoother way above mentioned guidelines along with course of actions are very much worth in all the way. In order to maintain the scenario in great and better way these process flows are very much effective in all the way. In order to make the functions working proper and precise above reasons are worth in all the way. Therefore this is obviously proper and precise way out to do well in all the way to all. Thanks for sharing the options to all
