👉 The term "non-interacting" is a concept in physics that refers to two systems (or particles) being able to interact with each other but not bring them into contact. In simple terms, it means that the system has no interaction or mutual influence with its surroundings. This can happen due to various factors such as quantum mechanics, statistical mechanics, and thermodynamics. For example, in a system where two particles are at rest relative to one another, they cannot interact because their motion is completely independent
