energetic

The team describes this unusual state as "highly energetic."

Instead of producing a reflex like Pavlov's dogs, the turtles respond with an energetic "dance."

"Despite the problems, the team managed to get organised and score a lot a of tries against an energetic Australian team."

Most Supernovae come from the energetic ending of massive stars, but one very important variety comes from a small and unlikely source: the humble White Dwarf.

From the central star, two cones of material are flung out into space in opposite directions, in a butterfly-like pattern, while smaller, more energetic jets of material fly straight out of the star.
