The breaking performance of the hemispherical lifter and the ladder lifter was poor, because the main pattern of motion was grinding rather than impact breakage. Secondly, the effects of the height–width ratio of the rectangular lifter, the height of the lifter and the number of lifters on the working efficiency of the ball mill were studied.

can conveniently describe the motion of a pitched ball to a rst approximation by ignoring the aerodynamics. As a separate issue, is not di cult to calculate the deviation caused by an additional N sideways or vertical lift force acting on a 145 g mass while the ball is traveling to the batter. The answer is s= 0:5at2 where a= F=m. The deviation caused

Motion Diagrams The particle model represents a moving object as if all its mass were concentrated at a si ngle point. Using this model, we can represent motion with a motion diagram, where dots indicate the object's positions at successive times. In a motion diagram, the time interval between successive dots is always the same.
