Accuracy of Simulations

Simulations of the flight of baseballs were used throughout this book and they are also used by Major League Baseball where television broadcasts and internet sites frequently present simulations of the trajectories of batted balls, particularly of home runs. This chapter investigates the accuracy of these simulations. It shows that the most important uncontrolled parameters are the CoR and the wind velocity. It emphasizes that to be correct, the simulations should measure and state values for the CoR, Wind velocity, Air density, Initial spin of the batted ball, Launch speed, the Drag coefficient and the Weight of the baseball.
