机械能是高中物理所研究的最重要的一种能量,存在于每个运动的物体中,机械能损失的原因有很多,有些直观一些,有些隐蔽一些,然而有3个瞬间的机械能损失应引起特别关注,历年来是高考命题的意向所在.1机械能损失在细绳张紧瞬间细绳在高中物理中是一种理想化的模型,它的质量和伸长量忽略不计,在与物体发生相互作用时,细绳对物体施 Mechanical energy is the most important kind of energy studied in high school physics. It exists in every moving object. There are many reasons for mechanical energy loss, some of them are intuitive and some are hidden. However, there are 3 moments of mechanical energy loss that should cause special attention , Over the years is the intention of the college entrance examination proposition.1 The loss of mechanical energy In the moment of thin rope tension is an idealized model in high school physics, its quality and elongation negligible, in the interaction with the object, String on the object facilities
