微积分作为一种重要的数学方法,不只在大学物理中的应用十分广泛,在高中物理中微积分思想也有很多应用,并且在高考试题中也时有出现。一、高中物理教学中常见的微积分应用1.微元法定义瞬时速度在高中物理学习之初瞬时速度的定义中就涉及微积分思想,求物体在某处的瞬时速度,可在该点附近取一段位移除以对应的时间即可得到该段位移的平均速度,所取的位移越小,其对应的时间越小,所得到的平均速度越接近所求点的瞬时速度,当所取位移近似为零时,所得到的平均速度即可认为是所求点的瞬时速
Calculus, as an important mathematical method, not only has a wide range of applications in college physics, but also has many applications in the physics of high school. It also has many applications in college entrance examination questions. First, the common high school physics teaching calculus 1. Micro-definition of instantaneous speed in the high school physics at the beginning of the instantaneous speed of the definition of calculus involved in the idea of seeking an object at some instantaneous speed, near the point Take a bit removed to the corresponding time to get the displacement of the average speed, the smaller the displacement taken, the smaller the corresponding time, the resulting average speed closer to the point of the instantaneous speed, when the displacement taken Approximately zero, the resulting average speed can be considered as the requested instantaneous speed
