kinetic friction
What kinetic friction means in Mathematics A-Level, as defined for WJEC.
Definition of kinetic friction
Check what you remember
Read the wording for your board, then hide it and explain kinetic friction in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
Dynamic friction acts parallel to the contact surface in the direction directly opposing the relative motion, operating at its maximum value F = μR because active sliding occurs.
