FBD Nomenclature

Disclaimer: WORK IN PROGRESS

This table will be updated regularly in the coming months as I work through problems with students on homework and test preparation. Desmos solutions posted on this blog will aim to use this nomenclature consistently.

Suggested Desmos variables nomenclature for AP Physics 'Free Body Diagrams' (FBDs), respecting Desmos calculator's built-in variable-naming limitations.  

For example:
  • Desmos does NOT allow subscripted or superscripted Greek letters or punctuation characters
  • All sub- and superscripts must be either upper- or lower-case letters, or integers
  • Desmos imposes limitations on θ all by itself, requiring a subscript for general usage
