1、Kinematics is the branch of physics that deals with the motion of objects without considering the forces that cause the motion.
运动学是物理学的一个分支，研究物体的运动，而不考虑引起运动的力。
2、In classical mechanics, kinematics is used to describe the motion of particles, rigid bodies, and systems of particles without considering the forces involved.
在经典力学中，运动学被用来描述粒子、刚体和粒子系统的运动，而不考虑涉及的力。
