Gravitational potential well means that energy cannot be transformed into another form of energy because it is trapped by the potential well, that iskinetic energyTherefore, an object will not reach the global potential energy extreme value, because it is based onentropyThe principle of is naturally inclined to this.
Chinese name
Gravitational potential well
Definition
Since it is trapped by the potential well, the energy cannot be converted into another form of energy
potential well（English：Potential well）Is a minimum surrounding the localpotential energyArea of.
When a particle moves in a force field, the potential energy function curve has the smallest potential energy within a limited range of space, which is shaped like a trap. The so-called potential trap is that the potential energy image of the electron is similar to the shape of a wave. When the electron is in a wave trough, it is like being in a well, which is relatively stable, and it is difficult to run out.So it is called potential well.Not only does quantum mechanics have this potential well, but any form of potential that has this shape can be called a potential well, such as a gravitational potential well.There is a small difference between quantum mechanics and classical physicsquantum mechanicsThe electrons have certain probability to run out through the potential well, which is calledTunnel effect。Tunnelelectron microscopeIs to use this principle
