课程介绍:
物理是一年级第一学期的课程,提供了一个经典力学的引进。它涵盖了牛顿力学,流体力学,气体动理论的基本概念。
8.01SC和8.01是不同的。8.01SC每个文件播放的时间比较短。
“力学”这个名词,在这里是指物体的运动:我们将研究对象的议案如何理解和预测的力量,在对象上。形容词“经典”,在这种情况下,这意味着我们会限制我们的研究相比,光的速度缓慢的速度,所以我们不会考虑到相对论的影响。这也意味着,我们会限制我们的研究对象一般都很大,比原子或分子,这样我们就不需要考虑量子理论的影响。幸运的是,我们有可能在日常生活中,以满足几乎任何情况下满足这些限制,因此,经典力学的结果有一个科学和工程应用的多种。
