本讲包括静力学、运动学和动力学。即大纲(1986年12月版)中的:一、力物体的平衡,二、直线运动;三、力和运动;五、曲线运动万有引力;七、振动和波等章内容。 tⅠ、复习要点一、知识结构: 力是改变物体运动状态即产生加速度的原因,物体的运动状态决定于力的作用效果。因此,本讲知识可以牛顿运动定律为主线,从运动状态和运动本质两方面加以整理归纳如下表。二、重要概念和规律: (一)重要概念 1.力、力矩、力偶
This lecture includes statics, kinematics, and dynamics. That is, the outline (December 1986 edition): First, the balance of force objects, Second, linear motion; Third, force and movement; Fifth, the universal motion of curve motion; Seven, vibration and wave chapter content. tI, review points First, the knowledge structure: Force is to change the state of motion of the object that is the cause of acceleration, the state of motion of the object is determined by the effect of force. Therefore, this lecture can be based on Newton’s laws of motion, and it can be summarized from the following two aspects: the state of movement and the nature of the movement. Second, important concepts and laws: (A) important concepts 1. Force, moment, force couple
