be used to measure velocity?
This is an informative site about how high-speed rail and magnetic
levitation work. What is the estimated maximum speed of a mag-lev
This is a brief, but efficient explanation of how a mechanical
speedometer works. Visit this site and determine if this is
measuring speed or velocity.
