Resultant force and motion
What Resultant force and motion means in Physics A-Level, as defined for OCR.
Definition of Resultant force and motion
Check what you remember
Read the wording for your board, then hide it and explain Resultant force and motion in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A body remains at rest or moves with constant velocity unless acted on by a resultant force, so zero net force means zero acceleration.
