You hold the camera, yes? That is the point of rotation. The further away you move the weight from that point, the harder it is to keep the camera pointing horizontal, the more force you have to apply to counter that the lens is going to point downward (the rotation I mentioned). You have to "counter" the rotation with your hands, with your muscles.

I understand you didn't study English physics definitions in your youth ...... 
 ......  but, I think the whole point of the language of physics is, we all use exactly the same terms and definitions ........and exactly the same text ..... and that means the same words !!

 in early classes we all spent time repeating "definitions" parrot fashion in the classroom ad infinitum and rote learned ........ until finally it was drummed into us ....... so no matter where you go or whoever the scientist you talk to, the underlying meaning was never in doubt .

  ........ by the same token ........  I rarely use scientific terms in the French language ...... I just don't have the background in French school physics .... and I hardly know any French who have anyway ....
so I don't ....

It's a tough call to be a technical author of English physics ...... a trade all of it's own!! ....... and I'm certainly not up to it .......
