A question I'm embarrased to ask - earth's spin
If it was weightless, gravity could not act on it.
"If it were..." (not "if it was..."). Don't confuse weightless with massless. Mass is the quantity that is conserved, and gives inertia. Weight is the =force= due to gravity on that object. In a free falling frame, an object is weighless, despite its mass. Jose -- "There are 3 secrets to the perfect landing. Unfortunately, nobody knows what they are." - (mike). for Email, make the obvious change in the address.
