interactions

Interactions refer to the ways in which two or more things influence or affect each other. They can occur between people, objects, or ideas, where each element's behavior or outcome depends on the presence or action of the other. For example, in science, interactions might describe how chemicals react with each other, or how different forces like gravity and friction work together. Understanding interactions helps us see how parts of a system connect and impact one another, revealing the complexity and dynamics of the world around us.
