滑 雪
第21届冬奥会在加拿大温哥华落下了帷幕,中国体育代表团在本届冬奥会上夺得了5金2银4铜的优异成绩,排在了奖牌榜的第七位,创造了历史新高.
当滑雪者从雪山顶峰风驰电掣般下滑时(如图),你是否想到为什么白雪轻飘飘、软绵绵的,却可以承托高速奔驰的滑雪者呢?
白雪内右很多小孔,小孔内充满空气.踏着滑雪板的人把重都压在滑雪板上时,雪内的空气就会被逼出;因此,滑雪板不是与雪地直接接触,而是在一层气垫上滑行.这层气垫不但对滑雪板施加一个向上的托力,并且减小了雪地与滑雪板之间的摩擦.然而,这层气垫只能维持一段很短的时间.如果滑雪者在雪地上停留超过一秒,就会沉下去.
(1)滑雪者从雪山顶峰向下运动过程中,重力势能将______,动能将______,机械能______(选“增大”“减小”“不变”填).
(2)滑雪板可以轻易再雪地上滑行,是由于:______.
(3)若滑雪板的长1.5m、宽12cm,滑雪者的速度最小为______m/s,他才能不会在雪地上下沉.
(4)若滑雪者与滑雪板总重为720N,当其站立再水平雪地上时,滑雪板对雪地的压强为______Pa.
