This research is about Energy Conversion of shape when dropped from a height and purposed to experiment about the best mathematical shape that can support object falling from the height and about energy transforming or energy conservation by the randomized experiment. The experiment is divided into 2 parts. The Equipment in this experiment is Clay , weighing machine ,A4 paper, glue, scissors, tape and rope. The statistics for analysis is Basic statistics, the average of the formula x ̅= Σx/Ν A result of the first experiment, cone was the best supporter. The object inside the cone maintained in the same shape because some of gravitational potential energy was transformed to elastic potential energy that the edge of the cone was shorten. A result the second experiment, we dropped cone with the object inside from different heights. We found that at the height of 9.15 meters, the object was still in the same shape, but at the height of 11.90 meters, the object was damaged.
