The proper term is “Newton’s _law_ of universal _gravitation_”.

<https://en.wikipedia.org/wiki/Newton%27s_law_of_universal_gravitation>

And the corresponding equation is

  F = G m₁ m₂∕r²

or

  F = G m_1 m_2∕r^2

instead (parentheses are optional).  While it is not necessary to use the 
proper Unicode characters, it *is* necessary to write subscripts 
*differently* than superscripts, especially if the latter are *exponents*; 
here, it is necessary to make the force F that the two bodies, with masses 
m₁ and m₂ respectively, exert on each other inversely proportional to the 
*square* of the distance r between their centers.

Such obvious imprecision is the mark of the wannabe and the crackpot.
