Modern tennis sport is characterized by constant change in several

directions. The most significant of these changes are connected to the design of tennis rackets.

The composite material of the rocket’s frame is continuously improved. It is also working

hard on improving the tennis strings. Tennis balls are also being modified. All these

innovations lead to a change in the shot technique of the athletes. Modern tennis players use

a variety of strokes. From the physical point of view, these blows can be classified into eight

main groups depending on the way the racket interacts with the tennis ball. These are the

strokes with top, bottom, side, top-side, and bottom-side rotation, as well as strokes without

rotation. These eight interactions lead to main types of trajectories at the same initial position

and the same initial linear velocity. The main purpose of the work is to study the two most

important strokes in professional tennis: forehand with upper rotation and backhand with

lower rotation. The calculations and graphical images are performed with the MatLab

mathematical package. The conclusions are important not only for specialists in the field of

Theoretical and Applied Mechanics, but they would also be useful for sports specialists,

coaches, and tennis players.
