In this note, we explore the powerful abstraction of energy—and its related properties and phenomena—covering energy and associated concepts as treated in thermodynamics.
NOTE: A VERY HARD AND SOPHISTICATED CONCEPT - https://curtjaimungal.substack.com/p/what-is-energy-actually
Energy is the interaction and motion of fields (at the deepest level of reality).
Energy is a property of matter and is not itself matter in the traditional sense. It can be thought of as the capacity to do work or produce change. While energy itself does not have mass, it can contribute to the mass of a system due to its equivalence with mass, as described by Einstein's theory of relativity.
The common denominator in all forms of energy is that they are all manifestations of the ability to do work or cause change. Energy can take many different forms, such as kinetic energy, potential energy, thermal energy, electromagnetic energy, and chemical energy, among others. However, no matter what form it takes, energy is always associated with the ability to cause changes in matter or other forms of energy.
A type of energy is a specific form or manifestation of the capacity to do work or produce change within a physical system, such as kinetic energy, potential energy, thermal energy, or electromagnetic energy.
A thermodynamic system is a physical or conceptual entity that is described by a set of macroscopic state variables, and its behavior is governed by the conservation of energy, the laws of entropy, and equilibrium conditions. These systems can interact with their surroundings through energy or matter exchanges, and they are classified into different types based on these interactions.
