👉 Unpropagable is a technical concept in physics and engineering, meaning that an object cannot be propagated or transferred. In other words, it's impossible for something to move from one point to another without being influenced by external forces. For example, if you have two objects moving towards each other, the first object will always move faster than the second due to gravity, but this is not possible when both are unpropagable. This concept is often used in physics and engineering fields to model situations
