: Who can explain the meaning of the gravitation constant? I know that it is equal to 6.67x10-11
: but what does it mean, is there a known equation from which we can obtain G, other than newton's equation?
:The constant G that appears in newton's law of universal gravitation F= G Mm/r^2, is called the universal gravitational constant because it has the same value for all pairs of particles anywhere in the universe, no matter what their separation. The value G was first measured by English scientist CAvendish, more than a century after Newton proposed his law of universal gravitation.
