Operation. The efficiency of a ball can be calculated by dropping and measuring the height of the bounce. The higher the bounce, the more efficient the ball is. Balls which do not bounce high are less efficient as they have lost energy. If theoretically a ball could not lose any energy during a bounce, it would bounce back to 100% of the height
