WebDisplacement is a vector, and therefore must incorporate direction. Distance is scalar, and does not need direction. For example, if you walk 5 meters to the right, stop, and then walk 5 meters left (back to the same point you started from) you walked 10 meters. That would be your distance. However, your displacement would be zero, because it ... WebDirection of radius, velocity and acceleration vectors in uniform circular motion. Angular motion variables.
