What should i find the center of gravity of?
The relationship between the Sun’s and Earth’s center of gravity, or maybe the the Earth’s and Moon’s center of gravity, or maybe even the Sun and Jupiter! Challenge yourself!!! Their respective center of gravities “change,” when showing where their mutual center of gravity, or barycenter(sp?), is actually located. This kind of assignment will probably both surprise you and also be a great lesson for others as well as being pretty easy to demonstrate gravitational interactions of simply two bodies in our solar system. Just glue it on a piece of cardboard, poster board, or even a sheet of notebook paper after you cut/draw them out. Google barycenter(sp?) or or center of gravity between planets… something like that, I am sure you’ll find out how to do it. By the way, the barycenter (sp?) of the Earth and Moon is actually located “within” the Earth itself. Have fun and shoot for an -A-!!! I mean you got all weekend now.
