Rotational Motion                                   baseball_image.gif                                                                 Introduction     Understanding how objects rotate and how this rotation affects translational motion is an important aspect to grasp in physics.  Rotational motion is something that is used to describe the motion of planets orbiting the sun as well as helping to explain why an object may be deflected in a particular direction.  What this cite will try to explain is the affects of a baseball pitcher rotating a baseball and why these individuals are capable of causing the changes in translational motion.  To to explain these affects, two different types of commonly used pitches will be addressed, the rising fastball and the curve ball.
