1. 刚体变换(Rigid Body Transformations) 在欧几里得空间中运动的粒子的运动描述是通过给出粒子在每一时刻相对于惯性笛卡尔坐标系的位置来实现的。具体来说,我们选择一组三个正交坐标轴,使用三维数组(x,y,z)∈R3 指定粒子的位置,其中每个坐标表示粒子位置在相应坐标轴上的投影。粒子的轨迹由参数化曲线 p(t)=(x...

3 空间R3中的刚性运动(Rigid Motion inR3) 回想一下第一节,刚性运动是保持点之间的距离和向量之间的角度的运动。我们通过使用刚体变换来描述刚体坐标系相对于惯性坐标系的瞬时位置和方向,从而表示刚性运动。这种表示依赖于这样一个事实,即刚体变换将右手系的正交坐标系映射到右手系的正交坐标系,从而保持距离和角度。
Even a huge body such as the earth, can be looked upon as a point mass, for example when its fundamental motion about the sun is investigated.This is a preview of subscription content, log in via an institution to check access.
