We found out that gravitational potential (stored) energy turns to kinetic (moving) energy when the balls are released and swing.
Energy is transferred through collision of the metal balls and the momentum (conservation of energy) keeps the potential / kinetic relationship going for quite a while.
Eventually the system comes to a stop due to heat and friction which means energy is lost from the cradle itself.
