Component, Unit, and R Position Vectors (12:31)
Vector components are reviewed. Unit vectors are introduced and an example is walked through. The “r” position vector is introduced and an example using both “r” position vector and unit vectors is worked through. This is an AP Physics C: Mechanics topic.
