momentum n.势头；动力；（物理）动量 (1) 在比赛的下半场，他们的势头就逐渐减弱。(2) 我们应继续保持良好的增长势头。(3) 我现在每天都会获得动力。(4) 和平运动获得了动力。(5) 雪橇从山上下冲时动量越来越大。(6) 下落的物体落下时动量增加。(7) 石头滚下山时，它的动量增加。 To find an object's physical momentum you multiply its mass by its velocity. Determining the momentum of the economy or the latest fad is much more difficult. Used figuratively, momentum implies that, like a boulder rolling down a hill, something with momentum will continue moving forward on its own. If you're running for class president, you might want to build momentum by holding a few rallies, passing out flyers and starting a website.
