Yoda - in response to post #184.

My comment about a centripetal force moving outwards along the string was plain stupidity!!!

No, Jeff, you just made a mistake. We all make mistakes. It's the way we learn.

I believe that there is no centripetal force moving in either direction along the string.

More yet to learn.

I believe that centripetal force is better defined as a force that causes an orbiting object to travel in a circular path rather than a straight line path.

Gettin' there now.

Consider my orbiting ball example again.

Thanks, Jeff, but no thanks. I'll leave that privilege for others.
