Newton's Law of Gravity is what can we say about the law, and about G? Check the 4 correct statements. There will be partial credit if you miss some. We must find G by making precision experimental measurements because we do not know its value otherwise. All evidence suggests that It is the same everywhere, for all time Its value sets the "size" or "strength" of gravitational force We can calculate G from first principles and understand why it has the value it does. This law of gravity only works near Earth. In space far from Earth there is no gravity. It may not apply very close to very large masses where General Relativity takes over as a better description.
