Fascinated with the way a soccer ball can deviate from a straight trajectory when it has angular velocity (and is subject to the Magnus effect), I have tried to make, as realistically as possible, a model of the free kick in soccer. All elements are taken into account, including placing the ball, the initial velocity (hitting the target is not guaranteed when following the ordinary procedure), choosing a target on the goal, and positioning the kick with "index-velocity" in the advanced procedure. In both cases you set up the angular velocity, but with the advanced procedure, the angular velocity is always chosen to be in a better direction for reaching the goal.
