means The forces, pressures, and patterns of change that drive how a system, relationship, or situation behaves over time.

from From Greek 'dynamis' meaning power or force — the same root that gives us 'dynamite' and 'dynasty' (literally, a lineage that holds the power). The physics sense of 'dynamics,' the study of forces and motion, emerged in the 17th-18th centuries alongside the new mechanics of Newton and his contemporaries. From there it leaped from pulleys and planets into offices, families, and friendships — any place where invisible forces push things around.
