I am not sure of the proticol of quoting between topic but from the centrifugal force topic:

[quote]

Still, he uses the term centrifugal force on page 7-5, to explain the tides and the motion of the Earth, and he says that the moon's attraction on the Earth is balanced by the centrifugal force, just as the BA has done. If you accept Feynman as the ultimate authority, I think you'd have to accept BA's use of the term.

BA doesn't mention centrifugal force in the explanation the tides on the Earth, due to the moon, which is the problem I have with the explanation.
