What does energetic mean?
Energetic is an adjective describing something or someone marked by abundant energy, vitality, or vigorous effort. It applies most often to people and animals — an energetic child, an energetic dog — but extends naturally to performances, writing, music, campaigns, and other endeavors, as in 'an energetic defense of her position'. The word carries a strongly positive connotation, suggesting enthusiasm and drive rather than mere restlessness, though context can shade it toward frenzied or exhausting when the energy seems excessive. It derives ultimately from the Greek energeia, meaning activity or operation, a term Aristotle used to describe being-at-work, and entered English in the early seventeenth century. Its common derivatives include the adverb energetically and the noun energy itself, making energetic part of a rich family of words concerned with power, work, and vitality in both everyday speech and scientific language.
Having or showing much energy; vigorous, active, and full of vitality.
"An energetic crowd cheered the team onto the pitch."
Often intensified as 'highly energetic' or paired with 'and enthusiastic'.
(Of an action, measure, or effort) Characterized by great force, intensity, or determined exertion.
"She launched an energetic campaign against corruption."
Borrowed straight from the Greek 'energeia' — the very word Aristotle used for being-in-action — 'energetic' has meant 'full of go' in English since the 1600s.

Etymology of energetic
Energetic comes from the Greek energeia (activity, operation), formed from energos meaning 'active, at work', which combines en- ('in') with ergon ('work'). The Greek root passed into Latin and then into French before entering English in the early seventeenth century, initially carrying philosophical senses related to effective action before settling into its modern sense of vigorous liveliness. It shares its ultimate root ergon with words such as energy, synergy, ergonomic, and even surgery (via Greek cheirourgia, handiwork).
