自然界存在的现象,与我们的生活紧密相连,在生产生活的实践中我们逐步摸索出了力学的规律,再让这些规律服务于我们人类,它给我们的生活带来了翻天覆地的变化,无论是日常生活、体育运动还是桥梁的建设都与力学息息相关。现将我在教学中的发现和在生活中的观察和理解做如下分析:1.日常生活中的力学1.1重力工人师傅在砌墙时,常常利用重锤线来检验墙身是否竖直,这是充分利用重力的方向是竖直向下这一原理。气球能在空中飞,是给气
The phenomenon that exists in nature is closely linked with our life. In the practice of production and life, we gradually find out the laws of mechanics, and let these laws serve our humankind. It has brought about tremendous changes in our life. Everyday life, sports or bridge construction are closely related to mechanics. Now I found in teaching and observation in life and make the following analysis: 1. Mechanics in daily life 1.1 Gravity workers in the wall, often using the heavy hammer line to check whether the vertical wall, which Is the principle of full use of gravity is vertical downward direction. Balloon can fly in the air, is to the gas
