I'm working through a chapter about forces and I was wondering about the definition of gravitational force of which things of mass are brought together. When thinking about the solar-system this "feels" some kind of intuitive to imagine the gravitational idea. But it makes me curious if this would also work in a smaller version:
Would it be possible to build a tiny model of the solar system made by a bowling ball and a tennis ball keeping the proportion in radius and mass of the objects at some place somewhere in the universe? And would be it be further possible to "stick" an extremely tiny object on the bowling ball and it would stay there just by the gravitation of the bowling ball?
Of course I know there would occur problems to install this model since every tool and the person itself would come up with gravitational forces ruining the model. As well as there mustn't be any object of mass somewhere next to my model.
Hope this one doesn't sound silly, since this is a rather elementary question but I was curious.
