Seems like a dreary definition to me. These so-called "human fabricated concpets" are mere descriptions to real phenomena which is observed in nature. As with all things in nature we give them names so as to create a universal language of terminology so that we're all on the same page.QuantumKing said:
but what about the redundance in the wikipedia definition of physics?pmb_phy said:
I would say no, because light has no rest mass, for example, so there is an effective difference between mass and energy.bernhard.rothenstein said:

Physics is the branch of science that deals with matter, energy, and their interactions. It is concerned with understanding the fundamental laws and principles that govern the behavior of the physical world.
In physics, matter is anything that has mass and takes up space. It can exist in various states, such as solid, liquid, gas, or plasma, and is composed of atoms and molecules.
Energy is the ability to do work or cause change. In physics, it is classified into different forms, such as kinetic, potential, thermal, and electromagnetic energy.
Relativity is a theory developed by Albert Einstein that explains how objects behave in the presence of gravity and at high speeds. It is based on the concept that the laws of physics are the same for all observers, regardless of their relative motion.
In physics, matter and energy are considered to be two sides of the same coin, as they can be converted into each other. Relativity, on the other hand, provides a framework for understanding the behavior of matter and energy in the presence of gravitational and high-speed effects.
