1 高中物理知识点总结一、静力学1.胡克定律：F=kx (x为伸长量或压缩量；k 为劲度系数，只与弹簧的原长、粗细和材料有关)2.重力：G=mg (g随离地面高度、纬度、地质结构而变化；重力约等于地面上物体受到的地球引力)3几个力平衡，则一个力是与其它力合力平衡的力。4两个力的合力：F(max)-F(min)F 合F(max)+F(min)。三个大小相等的共面共点力平衡，力之间的夹角为120，求F1、F2两个共点力的合力：利用平行四边形定则。注意：(1)力的合成和分解都均遵从平行四边行法则。(2)两个力的合力范围：F1 F2 F F1+F2(3)合力大小可以大于分力、也可以小于分力、也可以等于分力。5力的合成和分解是一种等效代换，分力与合力都不是真实的力，求合力和分力是处理力学问题时的一种方法、手段。6两个平衡条件：（1）共点力作用下物体的平衡条件：静止或匀速直线运动的物体，所受合外力为零。F合=0 或：Fx 合=0 Fy 合=0 推论：1 非平行的三个力作用于物体而平衡，则这三个力一定共点。2

3（拉密定理,对比一下正弦定理）文字表述:三个力作用于物体上达到平衡时，则三个力应在同一平面内，其作用线必交于一点，且每一个力必和其它两力间夹角之正弦成正比7物体沿斜面匀速下滑，则u=tan 8、摩擦力的公式：(1)滑动摩擦力：f=FN说明：FN为接触面间的弹力，可以大于G；也可以等于G;也可以小于G 为滑动摩擦因数，只与接触面材料和粗糙程度有关，与接触面积大小、接触面相对运动快慢以及正压力N无关.(2)静摩擦力：其大小与其他力有关，由物体的平衡条件或牛顿第二定律求解,不与正压力成正比.大小范围：Of静fm (fm为最大静摩擦力，与正压力有关)说明：a、摩擦力可以与运动方向相同，也可以与运动方向相反。b、摩擦力可以做正功，也可以做负功，还可以不做功。c、摩擦力的方向与物体间相对运动的方向或相对运动趋势的方向相反。d、静止的物体可以受滑动摩擦力的作用，运动的物体可以受静摩擦力的作用。9、浮力：F=gV

10、万有引力：F=Gm mr122(1)适用条件：两质点间的引力（或可以看作质点，如两个均匀球体）。(2)G为万有引力恒量，由卡文迪许用扭秤装置首先测量出。(3)在天体上的应用：（M-天体质量，m 卫星质量，R-天体半径，g-天体表面重力加速度，h卫星到天体表面的高度）a、万有引力=向心力GMmRhm()2VRhmRhmTRh222224()()()b、在地球表面附近，重力=万有引力

V=gRGMR/11两个一起运动的物体“刚好脱离”时：貌合神离，弹力为零。此时速度、加速度相等，此后不等。12轻绳不可伸长，其两端拉力大小相等，线上各点张力大小相等。因其形变被忽略，其拉力可以发生突变，“没有记忆力”。13轻弹簧两端弹力大小相等，弹簧的弹力不能发生突变。14轻杆能承受纵向拉力、压力，还能承受横向力。力可以发生突变，“没有记忆力”。15、轻杆一端连绞链，另一端受合力方向：沿杆方向。|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第
