angular momentum

The precise definition of the angular momentum of a body is complicated.

要给物体的角动量下精确的定义是困难的.

In Chap. 6 we shall generalize the discussion and take up angular momentum.

在第六章中我们将推广这一讨论,而且还将考虑角动量.

In undisturbed inertial motion, the angular momentum is constant.

在无扰动惯性运动中, 角动量是恒定的.

Angular momentum is an axial vector quantity.

角动量是一种轴矢量.

Angular momentum can accompany nonrotational motion.

非旋转的运动可能伴随着有角动量.

As a whole, the beam will therefore impart no total angular momentum to a target.

因此,整个说来, 这种光束将不传给靶任何总的角动量.

In other words, the magnitude of the angular momentum is increased, its direction remaining the same.

换句话说, 即角动量的大小增加了, 但其方向不变.

Angular momentum conservation is based on the isotropy of space.

角动量守恒是以空间的各向同性为基础的.

In this chapter we will discuss angular momentum.

本章将讨论角动量.

A swarm of planets absorbed most of the available angular momentum.

一大群行星吸收了大部分有效角动量.

The law of conservation of angular momentum may be demonstrated with a gyroscope.

角动量守恒定律,可以用回转器来演示.

The bland sameness of space is at the root of both momentum conservation and angular-momentum conservation.

平淡无奇的空间一致性,既是动量守恒的根本,又是角动量守恒的根本.

The farther out the line of the momentum extends the greater the angular momentum.

动量作用线伸展得越远,角动量就越大.

If the wheel is rotating counterclockwise, its angular-momentum vector is directed eastward.

如果轮子是逆时针方向旋转, 其角动量矢量的方向朝东.

Angular momentum and angular velocity are examined in a variety of problems.
