Abstract
AbstractThe most famous, common, but incorrect definition of the force “weight” is as follows: “Weight” is the force of interaction of a body with a support, caused by the force of gravity and directed vertically downward. This definition is used by artificial intelligence, models GPT-3.5 and GPT-4o. From the definition it follows that “weight” is only a load on the support. For example, a railway train loads the rails. This definition is supported by transport specialists, it is enshrined in textbooks, technical documentation and state regulatory documents. But in fact “weight” is an active driving force that completely determines the movement of a body along the support, describes its characteristics. “Weight” is the force of the double interaction of two bodies, which can arise under the influence of various factors, is not limited to the force of gravity. This is the author’s point of view. It is supported by physicists and scientists of theoretical mechanics (some). However, they avoid providing a definition of “weight”. The article is presented in the form of dialogues with artificial intelligence, in which the laws of interaction of material bodies are studied. The GRT-4o model initially quite confidently adhered to this generally accepted definition. Analyzing the action of "weight" together with the author, performing calculations and correcting errors, the AI step by step abandoned the incorrect definition. The article describes the communication methods and learning results. The understanding of the concept of "weight" is clarified, it is shown that "weight" is a complex force that combines a number of components. "Weight" fully determines the movement of the body along the support, corresponds to the definition of a generalized force, it should be used when compiling the equation of motion using the methods of classical mechanics, for example, using the Lagrange equation of the second kind.
