What is physical meaning?

Physical meaning refers to the interpretation and significance of a mathematical or scientific concept in terms of the physical world. It is the connection between theoretical knowledge and practical applications in physics, engineering, and other related fields. For example, in mechanics, physical meaning is the interpretation of Newton's laws and their applications in describing the motion of physical objects. In thermodynamics, it is the understanding of the relationship between energy, heat, and work. Physical meaning is essential in understanding and explaining the observations and phenomena observed in the real world and in developing new theories and models to explain these phenomena.
