👉 In physics, "potbellied" refers to a closed container that has two separate ends with a cylindrical shape. The two ends are connected by a gasket or a seal that prevents air from entering or leaving the container. For example, in a potbellied container, the top and bottom sections would be sealed off from each other to prevent air from leaking out of the container. This type of closed container is used for storing food, beverages, or liquids.
