We have heard many times that energy is involved in one or another physical process. We assume that energy is the true nature of matter and, of course, we have almost completely agreed with the opinion about the constant presence of energy in everyday physics. Just...What is energy?

One person once wrote in the comments that a self-respecting physicist would not define the term “energy.” Perhaps I will still dare to offer an intelligible description of this interesting physical entity. Moreover, we will select a clear analogy that will very well demonstrate the true essence of energy and its role in the surrounding reality. This video is the answer to many questions that constantly appear under this or that video, where they ask for an explanation of what energy can actually be.
