Universal Gravitation Constant - HELP!! Hello, I'm a little confused... What is the difference between the "Constant of Universal Gravitation" and the "Gravitational Force"? I know that there is a radius between two or more objects like the Earth and the Moon and bla bla bla... But the thing that I wanna know is the "Constant of Universal Gravitation". Is it the force between the two objects?? I would be grateful if someone could answer my question! Thanks!
