It demonstrates that one object can take part in the composition of two different aspects at the same time, and draws motion track directly. It is used in movement composition experiments of physics teaching. Two componential movements are uniform linear motions, or one is uniform linear motion, another is change speed linear motion (accelerating or decelerating).
