初中物理的教与学中,在学生掌握好物理的基本概念和基本规律的基础上,教学生充分利用数学知识,可以增强学生思维的灵活性,从而提高学生的理解能力和解题能力。下面就常数函数、一次函数、反比例函数和二次函数在初中物理中的应用各举一例。一、常数函数.例1:一辆汽车在一平直的公路上以20m/s速 In physics teaching and learning of junior high school, on the basis of mastering the basic concepts and basic laws of physics, teaching students to make full use of mathematics knowledge can enhance students ’flexibility of thinking so as to improve students’ ability of understanding and solving problems. The following on the constant function, a function, inverse function and quadratic function in the application of junior high school physics each give an example. First, the constant function. Example 1: a car on a straight road at 20m / s speed
