Hmmm ... OK. Sounds like I have my work cut out for me. Thanks, fellas. :)

Hopefully this is a pretty simple question, but I'm more a rock guy... :redface: CTT and TTA can both be used to make leucine. So to make leucine there is no difference to an organism's DNA whether it has CTT or TTA in the right place. But might the difference between CTT and TTA have other...

Oh. Then that's pretty darn simple then, ain't it?

Will this model work for my question? Is it a simple matter to convert the rotational energy into the gravity equivalent? Are there other models that do this for other situations? The situation I described does not require any rotation of the body, but I think I understand there might be the...

Hmmm .. OK. Thanks very much for the input. I will think this over.

OK .. let's ignore energy required to move the CG .. how much energy will be made available? What sort of maths do I need to do to to figure that out?

The gravity of the planet. The gravity of a planet is what makes it round. Agreed, but the kid on the see-saw is not in space. He's on earth. :) OK. When mass is moved from one side of a spherical planet to the other, that mass (actually - all the mass of the planet) is now available to...

OK, I'll fix my terminology .. actually, I'll describe a hypothetical .. it might help us more (see-saw comparison in brackets). Imagine a planetary mass that is the only matter in existence. Its own gravity is the only gravity it ever experiences. It is a perfect sphere and its mass is evenly...

Yeah .. http://exploration.grc.nasa.gov/education/rocket/moon.html" so I figure its CoG is as well. So I'm using the wrong term? I should say center of mass rather than gravity? I see this as a more complicated version of the see-saw experiment. The moon as a uniform sphere is like...

Cool. Now how about a large scale exercise...? The Center of Gravity of the moon is currently located slightly to the near side from the center of mass for the moon. Assuming the moon was originally perfectly spherical with the CoG located at the geometric center, how might we discover energy...

:smile: Oh, OK. The same calculation could be done knowing only the distance the center of gravity changed and the weight of the beam and kid, right? Thanks for your time.

I would like to discuss a physics problem. It's not homework or coursework. It's just an area of interest. I know there are models with which one may calculate a center of gravity for different 2d or 3d objects.. and .. I know that there are models to calculate available energy.. but I...
