Short-range interactions
What Short-range interactions means in Physics A-Level, as defined for OCR.
Definition of Short-range interactions
Check what you remember
Read the wording for your board, then hide it and explain Short-range interactions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The force is short-range, becoming negligible beyond about 3 fm, so only neighbouring nucleons interact strongly.
