👉 Vigorless is a term used in physics and engineering to describe an object or system that possesses no internal energy. It is often used in contexts where the object or system is not capable of performing work, such as in situations where there is insufficient external heat, light, or other sources of power. In simpler terms, vigorless objects are those that do not have sufficient kinetic energy to undergo any form of motion (such as a simple pendulum). They may also be described as having "no
