摘要
研究了滑块运动的第一种基本类型,即小滑块从光滑斜面滑向光滑水平面的运动,指出:滑块与光滑水平面发生了完全非弹性斜碰,故机械能不守恒,滑块在光滑水平面上的滑动速度u≠2gH,而是u=2gHcosθ.
This paper researches the first basic type of slider movement, namely the movement of a small slider sliding from a smooth slope to a smooth horizontal plane. Through exploration and study, this paper shows that completely inelastic oblique collision happens between the slider and the smooth horizontal plane, therefore the mechanical energy is not conserved, and the sliding velocity of the slider on the smooth horizontal plane,u≠2gH, butu=2gHcosθ.
