Can G be determined by measuring heat transfer in a controlled environment?

AI Thread Summary
Determining the value of G through heat transfer in a controlled environment is questioned, as gravitational force may not overcome static friction between two masses. The discussion emphasizes that without displacement, no work is done, meaning energy isn't changed, and thus no heat is generated. It is clarified that a force can be felt even if there is no movement, but for heat to dissipate through friction, work must be done. The concept of force is defined by its ability to change momentum, but without movement, it does not result in energy change. Overall, the feasibility of measuring G through this method remains doubtful.

Would it be possible to determine the value of G by setting two very well know masses side by side on a very well know surface of well known coefficient of friction, in a controlled environment, so that the force applied on the smaller by the larger would be transferred entirely into heat (minus any molecular rearrangements). And the amount of the heat change in the system could somehow indicate G?

I don't think the gravitational force between the masses(even if huge) would overcome even static friction in the first place. So no question of heat generation either.
 
If there's a tendency for force to pull regardless if it can, does that create energy being channeled into heat?

Force's tendency is to change the momentum. That is what defines it. And if there is no component of displacement in the direction of force, it doesn't do work. Meaning, it doesn't change the energy of the body on which it acts. In this case there is no displacement at all.
 
So If I attach a thick tight rubber band around my body and a telephone pole, I'm not moving towards it so you're saying I don't feel any force? I only feel force when I give into the pull of the rubber band??

If you are not moving then you are not experiencing a net force. For heat to be dissipated via friction you must be doing work, hence a force applied over distance.
 
I said the force wouldn't be doing any work. Didn't say anything about what you 'feel'. You feel a force when the part of your body subject to the force tries to move while the remaining parts oppose it, whether the entire body gives in or not.
