Force and motion
What Force and motion means in Physics A-Level, as defined for OCR.
Definition of Force and motion
Check what you remember
Read the wording for your board, then hide it and explain Force and motion in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
If the force and velocity are not in the same direction, only the component of force along the velocity contributes, so P = Fv cos θ.
