Definition of Negative potential near masses
Check what you remember
Read the wording for your board, then hide it and explain Negative potential near masses in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Because the gravitational force is attractive, the work done by the gravitational field is positive when moving from infinity to a point, so the potential is negative.
