**课程名称：** 线性运动运动学 **课程概述：** 本课程是力学（包括静力学和动力学）的基础入门课程。重点讲解动力学中的运动学部分，即在不考虑引起运动的力的前提下，研究物体的位移、速度和加速度。 **主要内容：** * **运动学基础：** 学习线性运动（直线运动）的基本概念。 * **匀加速直线运动与变速直线运动：** 区分这两种运动模式，并理解它们之间的差异。 * **重力作用下的运动：** * 理解重力（以牛顿或 kg m/s/s 为单位）与质量（以千克为单位）的区别。 * 了解重力加速度（m/s/s）的概念，以及在地球表面附近通常近似为 9.8 m/s/s（某些题目中可能使用 g=10 m/s/s）。 * 学习在忽略空气阻力（如真空环境下）的情况下，所有物体都以相同的速率下落，与它们的质量、形状和大小无关。 * 掌握与这些概念相关的各种问题。 * **运动图示：** 通过运动图示，更直观地理解运动学中的术语。 **学习建议：** 鼓励学习者仔细研读课程中的术语，以加深对基础概念的理解。
Mechanics gets classified into statics and dynamics. Dynamics may be broken down into kinematics and kinetics. Kinematics deal with displacement, velocities and accelerations without concern for the forces involved. Kinetics deal with the forces and moments involved in making the body move along with the measurement of various parameters describing the motion. Kinematics is included which studies the motion without considering the forces which caused the motion. In this course, learner will learn the basics of Kinematics of linear motion (i.e. the motion of the object in a straight line), the difference between uniform accelerated motion and variable accelerated motion, motion under gravity in which Weight is a force and is measured in Newtons or kg m/s/s. Mass is measured in kilograms (kg) and gravity is an acceleration (m/s/s). For objects reasonably close to the Earth's surface, gravity is approximated as 9.8 m/s/s (in some questions it may say use g=10 m/s/s). In the absence of air resistance, like in a vacuum, all objects will fall to the ground at the same rate regardless of their mass, shape and size and the problems associated with each term. Also at the last, motion diagrams are included for better graphical understanding of the terminologies. Learner is encouraged to go through the terms for better understanding of the basic concepts.
