position and velocity vectors
What position and velocity vectors means in Mathematics A-Level, as defined for WJEC.
Definition of position and velocity vectors
Check what you remember
Read the wording for your board, then hide it and explain position and velocity vectors in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
The vector velocity equation is v = u + at, and the vector displacement equation is r = ut + ½at², with position vector r = r₀ + ut + ½at² from initial position r₀.
