Causes of circular motion
... a rigid object is located along the line for which it will balance. As shown below, when gravity is the only force acting on a rotating object, it will rotate around its center of mass (technically that point would be the object’s center of gravity, but for this book you can treat center of mass and ...

Newton`s Second Law
... Examples A pitcher throws a fastball with a velocity of 43.5 m/s. It is determined that during the windup and delivery the ball covers a displacement of 2.5 meters. This is from the point behind the body to the point of release. Calculate the acceleration during his throwing motion. What do I know? ...
