中文简介:
由Tilahun Tesfaye撰写的Chimie Minerale 1模块。该模块(力学II)的核心概念是粒子系统,旋转运动和引力系统的动力学。该模块首先研究力的冲动及其与动量的关系。第二项活动是旋转运动的运动学和动态描述。引入并使用描述旋转运动的新量。将表明描述线性运动的运动方程具有旋转对应物。第三项活动是关于万有引力到目前为止,我们从完全经验的角度描述了各种力量。为了更加统一地理解这些力量并获得更大的预测能力,我们现在将研究最终对所有其他力量负责的四种基本力量中的两种。因此,在第三项活动中,很好地讨论了引力,它解释了所有天文体之间的相互作用,行星和月球的运动,太空飞行器的轨迹,潮汐的发生以及物体的重量。
课程简介: Chimie Minerale 1 Module authored by Tilahun Tesfaye. The central concepts of this module (Mechanics II) are dynamics of a system of particles, rotational motion and Gravitation. The module begins with the study of impulse of a force and its relation with momentum. The second activity is the kinematic and dynamic descriptions of rotational motion. New quantities to describe rotational motion are introduced and used. It will be show that the equations of motion that describe linear motion possess a rotational counterpart. The third activity is on Gravitation Up to now we have described various forces from an entirely empirical point of view. To gain a more unified understanding of such forces and to achieve greater predictive power, we shall now examine two of the four fundamental forces which are ultimately responsible for all other forces. Thus in the third activity well discuss the gravitational force which accounts for the interaction between all astronomical bodies, the motion of the planets and the moon, the trajectories of space vehicles, the occurrence of the tides, and the weights of objects.
