The forces or properties that stimulate growth, development, or change within a system. In physics, it refers to the branch of mechanics dealing with the motion of bodies under the action of forces.
From Greek 'dynamikos' meaning 'powerful', derived from 'dynamis' meaning 'power' or 'force'. The term entered English in the 1750s through scientific discourse, initially used in physics before expanding to describe any system of interacting forces.
The word 'dynamics' beautifully captures how ancient Greek concepts of power and force evolved into our modern understanding of everything from family relationships to rocket science. It's fascinating that the same word describes both the loudness variations in a Mozart symphony and the gravitational forces keeping planets in orbit.
