Physical Principles of the Submarine How Does a Submarine Work 2008 (1940)

Synopsis

The Submarine Part I: Physical Principles is a short Navy training film produced by Audio Productions, Inc. in 1940. The film, using animation, presents an overview of the key physical principles of how a submarine operates. The film starts with footage of a sub surfacing (00:37) before switching to animation to demonstrate the physical principles. First is Archimedes’ Law of Buoyancy (00:50) and Force of Buoyancy (02:00), as the film discusses how to change buoyancy through engineering water and air displacement. The film then discusses Fore and Aft Balance, based on Archimedes’ Law of the Lever (06:10); keeping the center of gravity in line with the center of buoyancy is how subs stay level. The film then quickly shows the effects of tilt on a sub (07:53), before ending the animation and concluding the film as it began—with footage of a submarine surfacing (10:35).
