谁都知道,顺风扬帆,乘风破浪,风对船帆的压力是推动帆船前进的动力.可是,如果遇上了逆风,帆船还能依靠风的力量前进吗?一般来说,逆风是帆船前进的阻力,但是如果选择合适的风帆方位,就可使逆风转化为帆船前进的动力.现在我们用简单的实验器材来做模拟小实验以获得逆风行舟的感性
Everyone knows that sailing in the wind, riding wind and waves, the pressure of the wind on the sails is the driving force behind the sailing. However, if the wind is up against the wind, sailing can rely on the strength of the wind? In general, the headwind is the resistance of sailing , but if you choose the right direction of the sail, you can turn the headwind into the power of the sailing boat. Now we use simple experimental equipment to do simulation experiments to obtain the sensibility of the sailing boat.
