A potential energy is the energy that an object has because of its position on a gradient of potential energy called a potential field, or just a potential.
An actual energy (E = hf) is a nonzero-frequency angular momentum.
A potential energy is the zero-frequency angular momentum stored in a potential flow of the vacuum.
The potential fields are irrotationally radial ("electric") fluxes of the vacuum and divide into two classes:
The gravitoelectric fields;
The electric fields.
The potential energy is negative. It is not a mere convention but a consequence of conservation of energy in the zero-energy universe—as an object descends into a potential field, its potential energy becomes more negative, while its actual energy becomes more positive.
In accordance with the minimum total potential energy principle, the universe's matter flows towards the minimum total potential energy. This cosmic flow is time.
