Inverse-distance dependence
What Inverse-distance dependence means in Physics A-Level, as defined for OCR.
Definition of Inverse-distance dependence
Check what you remember
Read the wording for your board, then hide it and explain Inverse-distance dependence in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Because E is inversely proportional to r, doubling the separation from r to 2r changes E from −GMm/r to −GMm/2r, an increase of GMm/2r.
