👉 In physics, "non-contact" refers to a system where there is no physical contact between two objects. In other words, when an object interacts with another object without any physical interaction (such as movement or motion), it does not experience any force or impulse from that other object. The term is often used in the context of mechanical systems where only one object can be acted upon by another. Example: - A door can be non-contact when you push on it, but there's no actual contact
