The document describes 4 motions with varying acceleration. Motion 1 slows down in the positive direction starting from rest. Motion 2 slows down in the negative direction. Motion 3 is the same as Motion 1. Motion 4 slows down in the negative direction, stops, and then speeds up in the positive direction with the same acceleration.
