Zero Gravity Physics Lesson

Col. Terry Virts (USAF) is an astronaut currently serving on the International Space Station. Chapple's Dictionary of Physics defines centripetal force as "a force that acts at right angles to a body's path and so constrains the body to follow a circular path about the point to which the centripetal force acts." That's a circle, which Col. Virts demonstrates nicely in zero gravity using a chain.

It's three degrees above zero here in Kentucky right now. I just realized I haven't been out of the house since Tuesday. That has less to do with the temperature than it has to do with the fact that two cars are in the shop.

That wasn't a "hose outlet" inside the house, it was the faucet of a laundry sink next to the washing machine, which is pretty common all over the U.S. They just used it because they would have already drained the water lines leading to the outside water taps (where the garden hose would be attached during the summer) in preparation for winter, so they needed an inside tap that had outside threads to couple with the hose. Ergo, the laundry sink.
