动力, 推动力
a forceful turn or spin in dance, often used in partner dances like waltz and foxtrot
An impetus is a movement or action that provides a driving force or momentum, often used to initiate a turn or transition. It typically involves a dynamic, forceful motion that propels the dancer into the next movement or direction. For example, in ballroom dancing, an impetus might be used to lead into a spin or to change the dancer's direction with a strong, controlled push. An impetus is crucial for creating smooth, energetic transitions and maintaining the flow of the dance.
