1)匀变速直线运动 1.平均速度V平=s/t(定义式) 2.有用推论Vt2-Vo2=2as 3.中间时刻速度Vt/2=V平=(Vt+Vo)/2 4.末速度Vt=Vo+at 5.中间位置速度Vs/2=[(Vo2+Vt2)/2]1/2 6.位移s=V平t=Vot+at2/2=Vt/2t 7.加速度a=(Vt-Vo)/t {以Vo为正方向,a与Vo同向(加速)a>0;反向则a<0} 8.实验用推论Δs=aT2 {Δs为连续相邻相等时间(T)内位移之差} 9.主要物理量及单位:初速度(Vo):m/s;加速度(a):m/s2;末速度(Vt):m/s;时间(t)秒(s)位移(s): ;米(m);路程:米;速度单位换算:1m/s=3.6km/h。 2)自由落体运动 1.初速度Vo=0 2.末速度Vt=gt 3.下落高度h=gt2/2(从Vo位置向下计算) 4.推论Vt2=2gh (1)自由落体运动是初速度为零的匀加速直线运动,遵循匀变速直线运动规律; (2)a=g=9.8m/s2≈10m/s2(重力加速度在赤道附近较小,在高山处比平地小,方向竖直向下)。 (3)竖直上抛运动 1.位移s=Vot-gt2/2 2.末速度Vt=Vo-gt (g=9.8m/s2≈10m/s2) 3.有用推论Vt2-Vo2=-2gs 4.上升最大高度Hm=Vo2/2g(抛出点算起) 5.往返时间t=2Vo/g (从抛出落回原位置的时间) (1)全过程处理:是匀减速直线运动,以向上为正方向,加速度取负值; (2)分段处理:向上为匀减速直线运动,向下为自由落体运动,具有对称性; (3)上升与下落过程具有对称性,如在同点速度等值反向等。 二、质点的运动(2)----曲线运动、万有引力 1)平抛运动 1.水平方向速度:Vx=Vo 2.竖直方向速度:Vy=gt 3.水平方向位移:x=Vot 4.竖直方向位移:y=gt2/2 5.运动时间t=(2y/g)1/2(通常又表示为(2h/g)1/2) 6.合速度Vt=(Vx2+Vy2)1/2=[Vo2+(gt)2]1/2 合速度方向与水平夹角β:tgβ=Vy/Vx=gt/V0 7.合位移:s=(x2+y2)1/2, 位移方向与水平夹角α:tgα=y/x=gt/2Vo 8.水平方向加速度:ax=0;竖直方向加速度:ay=g (1)平抛运动是匀变速曲线运动,加速度为g,通常可看作是水平方向的匀速直线运与竖直方向的自由落体运动的合成; (2)运动时间由下落高度h(y)决定与水平抛出速度无关; (3)θ与β的关系为tgβ=2tgα; (4)在平抛运动中时间t是解题关键;(5)做曲线运动的物体必有加速度,当速度方向与所受合力(加速度)方向不在同一直线上时,物体做曲线运动。 2)匀速圆周运动 1.线速度V=s/t=2πr/T 2.角速度ω=Φ/t=2π/T=2πf 3.向心加速度a=V2/r=ω2r=(2π/T)2r 4.向心力F心=mV2/r=mω2r=mr(2π/T)2=mωv=F合 力(常见的力、力的合成与分解)
