     (Relate average/instantaneous acceleration to the initial-to-final changes in velocity over elapsed/brief time intervals; distinguish between x, vx, v0x, ax and t labels so you are comfortable putting these values into the Table 2.1 equations (which you don't have to memorize); and at least know how to calculate areas or slopes of graphs (more specific details later in class).)
