    It says right on the webpage:
    The notes are based on lectures given to final year undergraduates during the fall of 2004 and 2005.​

    It's meant as a text for upper level undergrads, not high school students. (At least not the typical high school student.)

    The r with a dot means the derivative of r with respect to time, which is the velocity.
