waspy,
Your explanation is now finally clear, and also completely wrong.
Like the downwind turn, the concept of the machine inventing a force as it is being "swept through space" is a mis-reading of what an "inertial reference frame" is.
Please go back and look again at how Galileo and Newton defined the reference frames for their laws. A translating frame does NOT change the relationship. Otherwise our 33,000 mph trip around the sun would make a big difference in your tire wear as you turned certain corners!
Your analysis, and Jiff's device, are a lot of hooey. I think I will end my attempts to teach Physics 101 to the both of you.
Shytorque, remove that balance arm and hit them with it, please!
