What do the Symbols (r) and (m) Mean?

In summary, the book is intended for upper level undergraduate students and was based on lectures given in 2004 and 2005. The symbol "r" with a dot above it represents the derivative of r with respect to time, which is velocity. The book can be found at the URL www.damtp.cam.ac.uk/user/tong/dynamics.htm and is not meant for high school students.

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.)
