物理学中的“做功”和日常生活中的“做工”是两个不同的概念,生活中的“做工”是指人花了力气,完成了某项工作,也就是做事情.而物理学中的“做功”有严格定义,我们把作用在物体上的力和物体在力的方向上通过距离的乘积叫做力做的功,简称为功.由此可见,物理学中的做功应具备两个条件:一是对物体有力的作用,二是物体要在力的方向上通过一定的距离.所谓对物体有力的作用,即存在 The “work” in physics and the “workmanship” in daily life are two different concepts. In life, “workmanship” means that people have done their best to finish a certain task, that is, to do Things. “In physics, there is a strict definition of ” work ", we put the force acting on the object and the object in the direction of force through the product of the distance is called the work done by force, referred to as work. Thus, the physical Learning in the work should have two conditions: First, a powerful role in the object, and second, the object in the direction of force through a certain distance. The so-called powerful role of the object, that is,
