Top of the tire is doing double the cars pace, and the bottom is stationary, although only at that one instant when the points are TDC and BDC respectively. |

Is the question about speed or velocity?
Speed is found by dividing the circumference of the circle by the time taken to move around the circle |

Here's another point about points when we're discussing points in time. I like to mess with the scouts over stuff like this. 
If a point in time doesn't exist then it can never really BE that time. It's always before or after. Say, 5 o'clock. It's never actually 5 o'clock. Always before or after. Same principle can be used in measurement. Take a "5 inch long" steel bar. The bar will never be exactly 5 inches long. If you placed one end on plane zero, the plane of the other end of the bar will always be either short of or past the plane which is exactly 5 inches away from the first because that plane doesn't physically exist. |

I've often thought about fabricating a low observable motorcycle with RAM, and having the lower half of the front wheel exposed, hoping that the Doppler return off of the lower part of the wheel might be enough to bias the calculation low.
And then I got sidetracked designing an Electronic Warfare system, and incorporating EW apertures into the design. Given the limited alternator capacity of your average motorcycle, the solution was a pair of capacitor banks in the sidecases. And then there are the IR aspects and trying to balance those against LIDAR. It never ends! |

This is covered in the first week of calculus in the theory and application of limits. Where does the time just before and just after 5 o'clock converge? It converges to 5 o'clock. Same with the rule at the 5 inch plane, except we have to discriminate between a real ruler and a theoretical ruler with a length that is infinitesimally close to 5 inches. |

Apparently, the concept of zero is a fairly recent development. And a mindblowing one it is. The existence of zero as a place holder allows us to count higher than 9, and to contemplate complex mathematics. I saw that on the Science Channel. |
