This video compares two types of tennis serves: the flat serve and the kick serve. Flat serves are difficult to return because they are hit with a lot of pace. This significantly cuts down the amount of time an opponent has to prepare to hit. A kick serve, however, causes the tennis ball to "dance." The tennis ball curves in the air and bounces to the side. Thus - as we explain in the video - the two serves are difficult to return for different reasons.
