interaction?</h3>
A type of activity known as interaction takes place when two or more items have an impact on one another. In contrast to a one-way causal effect, the idea of a two-way effect is crucial to the concept of interaction. Interactivity and interconnection are closely related concepts; the latter deals with the interactions of interactions inside systems; combinations of numerous straightforward interactions might result in unexpected emergent phenomena.
In many sciences, interaction has numerous specialized meanings. A basic interaction in physics is the process by which elementary particles interact with one another. Depending on the interaction, it may also be referred to as a fundamental force. A physical field is frequently used to define an interaction, and gauge exchange serves as its mediator.
