If the planet is moving, the solar system is moving, and the galaxy is spinning, while moving, What's a ruff speed of a person? though, lets say im moving that way ---> at 100 mph. i then start to orbit with a diamiter of 100 meters, i cant see this happening with out my speed changing, other wise from a birds eye view i'd just be going left and right while going ---> http://homepage.ntlworld.com/ak_gara/spin.gif on the B part, would i be slowing down? on the A part, would i be speeding up? I'm guessing no, since there has to be something like drag to slow you down and something to add force to speed you up. but how would that work?
