the.com/dynamism

means The quality of being constantly active, forceful, and full of energetic change rather than settling into stillness.

from Traces back to Greek 'dynamis,' meaning power or force — the same root that gives us 'dynamic' and 'dynamite.' The word 'dynamism' itself emerged in the 19th century as philosophy needed a term for the idea that force and energy, not static matter, are the fundamental stuff of reality. It later loosened its grip on strict philosophy and became everyday shorthand for anyone or anything that refuses to sit still.
