Describe your change:

I implemented an algorithm to find out the values of either Force of attraction, distance or magnitude of any one of the masses of a two-body gravitational system using Newton's Universal Law of Gravitation, provided the values of the other three parameters are non-zero numbers.

Hey @cclauss, sorry for pinging. Could you please take a look at this PR?

Comment thread physics/newtons_law_of_gravitation.py Outdated
product_of_mass = mass_1 * mass_2

if (force, mass_1, mass_2, distance).count(0) != 1:
raise ValueError("Only one argument must be 0")

I don't know why it shows failing after the suggested change. Do you want me to commit the file from my local machine again? Because I committed the change from my browser.
