Bowlers run up before performing a little hop to get momentum going and bowl the ball. Does the run-up contribute anything to the speed/spin of the ball? Or could you get a similar speed/spin by just hopping to get your moment going, without running?
I know pitching in baseball is different from bowling in cricket, but wouldn't you be able to get a similar amount of force behind the ball without running up? Isn't energy lost by the hop that bowlers perform when they extend their legs and pivot with the ball?
