👉 Unrigidness is a concept in physics that refers to a property of matter or energy that prevents it from changing its state, such as by causing dissipation. In other words, it describes how an object remains at rest or at rest-like conditions when subjected to external forces, even though the internal structure or properties are not uniform and can vary across different parts of the object. This concept is important in understanding the behavior of objects under various physical conditions and in designing structures that can resist changes in
