SUMMARY

The discussion clarifies that the symbols (r) with a dot above it and (m) with a dot represent specific mathematical concepts in dynamics. The (r) symbol denotes the derivative of position with respect to time, indicating velocity. The conversation also establishes that the intended audience for the referenced book is upper-level undergraduate students, not high school students. The source of this information is a webpage from the University of Cambridge's Department of Applied Mathematics and Theoretical Physics.

PREREQUISITES
  • Understanding of basic calculus concepts, particularly derivatives.
  • Familiarity with dynamics and kinematics in physics.
  • Knowledge of notation used in mathematical physics.
  • Access to the specific lecture notes from the University of Cambridge.
NEXT STEPS
  • Review the University of Cambridge's dynamics lecture notes for further context.
  • Study the concept of derivatives in calculus, focusing on physical interpretations.
  • Explore advanced dynamics topics relevant to undergraduate physics courses.
  • Investigate the applications of velocity in real-world physics problems.
USEFUL FOR

This discussion is beneficial for undergraduate physics students, educators teaching dynamics, and anyone seeking to understand mathematical notation in physics contexts.

First of all, for what audience is the book intended for? I mean for high school students or undergrads?

2nd. I encountered a symbole (r) with a dot above it and also (m) with a dot too? what do these symoles mean??

thx

Huh? Which book?
 
the lectures from his site!
 
Can't you please give us the exact URL for the exact lecture and the exact page of what you are asking?
 
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.
 
thx doc!
