高中物理中功的概念,从教师到学生长期以来都有较多、较深的模糊之处,结合自己的教学实践和对概念形成过程的学习研究,特对青年教师作如下建议和交流。一、功的概念建立的缘起高中教材对功的概念的形成历史有一个简要的交代——早期工业革命促使人们需要一个衡量机械工作能力的统一标准,在此基础上人们逐渐形成一致意见,即用机器将重物提起的高度与重物重力的乘积作为一个标准,由此逐渐形成了功的概念。但是,这个交代,只说明了功的概念的建立历史和实际功用,
The concept of high school physics Zhong Gong, from teachers to students for a long time have more and more ambiguous place, combined with their own teaching practice and study of the concept of the formation process, especially for young teachers make the following recommendations and exchanges. First, the origin of the concept of the power of work The composition of high school teaching materials on the concept of power has a brief history of the history - the early industrial revolution prompted people to need a measure of mechanical work ability of a unified standard, based on which people gradually form a consensus that Using the machine to lift the weight of heavy objects and the product of gravity as a standard, which gradually formed the concept of work. However, this account only shows the establishment of the concept of the history of history and the actual function,
