角动量角动量angularmomentum描述物体转动状态的量。又称动量矩。如质点的质量为m,速度为v,它关于O点的矢径为r,则质点对O点的角动量L=r·mv。角动量是矢量,它通过O点某一轴上的投影就是质点对该轴的角动量(标量)。质点系或刚体对某点(或某轴)的角动量等于其中各质点的动量对该点(或该轴)之矩的矢量(或代数)和。一个质量为m的质点绕O点作半径为r的匀速圆周运动,转动角速度为ω,则质点对O点的角动量L=r·mv=r·mrω=mr2ω=I0ω,式中I0为质点对圆心O的转动惯量。以角速度ω绕定轴z转动的刚体,其中各点都分别在与z轴垂直的各平面上作匀速圆周运动,而它们的圆心就是各平面与z轴的交点。因此,刚体绕z轴转动的角动量L=ri·mivi=ri·miriω=miri2ω=Izω,式中Iz=miri2为刚体对z轴的转动惯量;ri、vi、mi分别为第i个作圆周运动的质点的半径、速度和质量。角动量的量纲为L2MT-1,其SI单位为kg·m2/s。
