interaction

Interaction refers to the way two or more elements influence or affect each other. It can occur between people, objects, or systems, where each component's behavior or outcome depends on the presence or actions of the other. For example, in a conversation, your words and responses impact the other's reactions. In science, interactions between particles or forces determine physical phenomena. Essentially, interaction describes a mutual influence that shapes how things behave or change, highlighting that events or elements don't operate in isolation but are connected through these influences.
