Definition of sign conventions
Check what you remember
Read the wording for your board, then hide it and explain sign conventions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
Consistent directional signs maintained throughout, for example upwards positive, so that vector quantities such as velocity and acceleration keep the correct signs.
