在解决物理问题的过程中,运甩数学方法,能够使物理规律精确定量地表述,达到物理科学严密完美统一的目的,正因如此,数学方法的灵活应用成为解决好物理问题的重要保障。基于此,中考物理试题中,计算题成为检测学生综合能力的重要题型,甚至使物理教学中计算题一度进入繁、偏、难的怪圈,演化成数学综合能力的大比拼,而偏离了初中物理教学的初衷。随着新课程的深入,运用物理规律进行的基本计算更灵活、更联系实际又成为新的特点,其中估算
In the process of solving physical problems, the mathematical method of transportation can accurately and quantitatively describe the laws of physics and achieve the purpose of strictly and perfectly unifying physical science. For this reason, the flexible application of mathematical methods has become an important guarantee for solving physical problems. Based on this, the senior high school entrance examination physics questions, the calculation questions as an important test of comprehensive ability of students, even the calculation of physics teaching problems once entered the complex, partial, difficult circle, evolved into comprehensive ability of mathematics competition, and deviated from the junior high school The original intention of physics teaching. With the deepening of the new curriculum, the basic calculation using the laws of physics is more flexible and more in line with reality has become a new feature, in which the estimated
