Newton's law F = -Gm₁m₂/r²

Better seen in its normal math form:
https://en.wikipedia.org/wiki/Newton%27s_law_of_universal_gravitation#Modern_form

De-abbreviated

Force is given by the negative of the universal_gravitational_constant times
the mass_of_first_body times mass_of_second_body divided by the square of the distance_between_the_bodies

Cobol anyone?

Ok with typical python naming

Force = (universal_gravitational_constant * mass_of_first_body * mass_of_second_body) / (distance_between_the_bodies*distance_between_the_bodies)
