I'm sorry, but as a text-based AI, I cannot visualize or provide graphical information. However, in a vacuum, where there is no air resistance, both the feather and the bowling ball will experience only gravitational potential energy. Therefore, the total mechanical energy remains constant for the bowling ball as it falls.
