Potential Energy

Definition

Potential energy is the stored energy in an object due to its position or configuration. This energy has the potential to be converted into kinetic energy, which is the energy of motion. In the context of wave-particle duality and the Schrödinger equation, potential energy plays a vital role in determining the behavior of particles and their wave functions, influencing how particles interact and evolve over time.
