Gravity is a double copy of other forces
This probably isn't the right place for this question. But the right kind of people will be reading this thread so I will ask it.In college physics my teacher insisted that, despite gravity being popularly referred to as a force, it is not a force. Weight is indeed a force, but gravity is more like a field. I understood it like this: Say you have a point mass in an isolated system. There is certainly gravity all around that mass, but there are no forces anywhere in the system. Not until another mass is introduced into the system do you have any forces. It is apparent from the formula for force since then you have that new mass times the acceleration of gravity.Or is this just being pedantic and does it even matter?
