👉 In physics, a "sheathless" object is an object that has no significant amount of mass or density. This means that all its components are essentially identical in size and shape, with no visible difference between them. For example, a solid sphere or a metallic bar would be considered sheathless, since they have the same volume and mass.
In other words, a "sheathless" object is one that does not exhibit any noticeable characteristics such as color, texture, or internal structure
