数学是物理学习的工具,学好数学是学好物理的重要基本条件.在初中阶段由于物理学科重在培养学生掌握基本规律和分析问题的能力,因此对物理习题的处理只涉及到简单的数学计算.但有些物理习题虽然较容易利用物理规律列出方程(组),但在解法上若无一定的技巧却是很难很快得出结果的.在热学中有这样的一道习题:为了测定熔炉的温度,先取一铂块,加热到熔炉温度相同,取出后立即放到水中,结果水温从15℃升
Mathematics is a tool for physics learning. Learning mathematics is an important basic condition for learning physics. Because the physics discipline focuses on cultivating students’ ability to master basic laws and analyze problems in the junior middle school, the processing of physics problems involves only simple mathematical calculations. However, although some physics exercises are easier to use to list the equations (groups) using physical laws, it is difficult to quickly obtain results if there is no certain skill in the solution. There is such an exercise in thermal science: to determine the furnace At the temperature, first take a platinum block, heat to the same temperature in the furnace, immediately remove the water after the removal, and the water temperature rises from 15°C.
