Calculating the amount of energy that your Rube Goldberg machine wasted" is a bit more
complicated. If your system was 100% efficient, then all of the potential energy stored in your
machine would be transferred to the motion of the ping-pong ball pendulum, and as the
ping-pong ball swung upward, its kinetic energy would be converted into gravitational potential
energy.
Based on the law of conservation of energy and the assumption that your system was 100%
efficient (meaning thay no energy was "wasted"), record your prediction for the height of the
ping-pong ball in the space below, and include the calculations that led you to your
