Ball is jerking, not turning. Only when it moves by it self, turning is smooth. (thank you, but ball isn't mine

only particles are mine). On the video you can see that there is a problem. That is not because of low frame rate (while recording video) and so on. You can see, that ball moves very smooth and good by it self (on the video -> 10 sec), after applying force to it, but while you are applying force, ball jerks (on the video -> 12 sec)
