Basic concepts of kinematics
The science of the relation between a given motion of an object and time. in which only the geometrical characteristics of the motion such as trajectories, velocities and accelerations, are studied, but not the reasons for the motion considered.
①Develops the methods for describing mechanical motions.
②Establishes the relations between the variables related to motion.
Foundations for the following courses and and direct applications in engineering practice.
Reference object; frame of reference system, frame of static reference System, moving frame of reference system.
1) Motion of a particles .
2)Motion of a rigid body .
Introduction
运动学
①运动学
②运动学研究的对象
③运动学学习目的
④运动是相对的
⑤瞬时、时间间隔
⑥运动分类
运动学的一些基本概念
是研究物体在空间位置随时间变化的几何性质的科学。
(包括:轨迹,速度,加速度等)不考虑运动的原因。
①建立机械运动的描述方法
②建立运动量之间的关系
为后续课打基础及直接运用于工程实际。
( relativity ):参考体(物);参考系;静系;动系。
1)点的运动 2)刚体的运动
