exchange force
Quick Summary
In physics, an exchange force is a force that arises between two elementary particles due to the continuous interchange of other particles between them. For example, a neutron and a proton can exert an exchange force on each other through the exchange of pions.1
This concept is related to the fundamental forces of nature, where interactions between particles are mediated by the exchange of specific force-carrying particles called gauge bosons. For instance, the electromagnetic force is mediated by photons, which are exchanged between electrically charged particles. These exchanges of virtual particles, governed by principles like Heisenberg's uncertainty principle, are what give rise to the forces we observe.2
