Displacement is a vector quantity, so it has both magnitude and direction. A vector can have a sign to show opposite directions. If a person goes 10 meters left and then 10 meters right, one of those directions has to be negative so that the net displacement is zero. What is the unit...
刚体力学:无限小角位移为什么是矢量Geostatics:Why Infinitesimal Angular Displacement is Vector 董铭瑒 领科教育北京校区A2年级 23 人赞同了该文章 0.前言 今天和朋友聊天聊到一个很有意思的问题,为什么刚体的无穷小转动是矢量,而有限大转动不是矢量,这里给出我想到的几种证明方法。1.证明过程: 以绕z 轴的转动矩...

Displacement is a vector and depends only on the final and initial points, not the path taken. Work is force across distance, not displacement. Jun 29, 2009 #1 Starproj 18 0 Hi, I am taking my first semester of physics this summer and am having trouble grasping what I imagine is ...
Ans. Displacement is a vector quantity. This means that it has direction and magnitude and is represented as an arro...Read full At which point, the displacement of an object is zero? Ans. When the endpoint and the first point of the object are the same then the displacement is called ...
