ABSTRACT: Modern tennis players use a variety of strokes. From the physical point of view, these shots can be classified into eight main groups depending on the way the racket interacts with the tennis ball. These are strokes with top, bottom, side, top-side, and bottom-side rotation, as well as strokes without rotation. These eight interactions lead to eight main types of trajectories at the same initial position and the same initial linear velocity. The main purpose of the study is to determine these trajectories and to describe their advantages and disadvantages in modern competitive tennis. The calculations and graphical images are performed with the MatLab mathematical package.
