Sign conventions and the zero of potential at infinity
What Sign conventions and the zero of potential at infinity means in Physics A-Level, as defined for AQA.
Definition of Sign conventions and the zero of potential at infinity
Check what you remember
Read the wording for your board, then hide it and explain Sign conventions and the zero of potential at infinity in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Gravitational potential is negative because the zero is defined at infinity, and V is always negative and rises towards zero as 1/r.
