Weight *is* the force of gravity on an object.

The force of gravity depends only on the masses of the objects in question
and the distance between their centres of gravity � the famous inverse
square law. The rotation of one or both of the objects has no effect on
the force of gravity between them.

I hope this helps any TIPSters who have to deal with this subject in the
course of teaching topics in psychology. :-)
