资源描述

牛顿第二定律初步应用,例1A:如图所示,位于水平面上质量m = 2.0 kg的小木块,在水平拉力作用下沿地面作匀速运动。若木块与地面间动摩擦因素为0.5 ,试求拉力大小。,例1B:如图所示,位于水平面上质量m = 2.0 kg的小木块,在水平拉力作用下沿地面从静止开始作匀加速直线运动,加速度大小是2m/s2。若木块与地面间动摩擦因素为0.5 ,试求拉力大小。(g=10 m/s2),例2A:质量为m的物块与水水平面间动摩擦因素为,在与水平面夹角斜向右上的拉力作用下,物体沿水平面向右匀速运动,求斜向上拉力大小?,例2B:质量为m=1kg的物块在与水平面夹角=370的拉力F=3N作用下,物体沿水平桌面向右做初速度为4.4m/s的匀减速运动。物块与水水平面间动摩擦因素为=0.4,求加速度的大小?(物体能够运动多久?) (g=10 m/s2),例3:如图所示,斜面倾角为=370,质量为10kg的物块放在斜面上,若给重物一个沿斜面向下的速度,重物沿斜面匀速下滑,求动摩擦因素。若动摩擦因数变为原来一半,则物块下滑的加速度?(g=10 m/s2),
