I've looked at a couple of the suggested previous discussions. While the questions are similar, if not the same in essence, I have not found a good answer. Allow me to first give you some background as to what I am asking. I have pondered this question day and night; it has often distracted me from coursework and other such tasks I need to complete. Unless I completely misunderstand the topic, energy is difficult to grasp intuitively. Now, yes I understand energy is a property of a particle or body. Yes, I understand that energy has formulaic definitions for many things in many subjects. Yes, I understand that energy "works" and does its job, whatever those mean. However, I am not looking for these answers. I am not looking for "energy is the capacity to do work". This is a recursive definition. Work is already energy, granted, sometimes it is only a fraction of the energy of a system, but it is already some of said energy. So, what I'm looking for is an inherent, intuitive, and abstract definition of energy. A definition that can be applied to most, if not all situations. Please do not respond that "this isn't possible" unless you have absolute proof that it is. Not only will this definition help me in my own discovery, but it could very well help many students who are trying to understand the topic. I look forward to your responses and interesting discussion.
