数学是物理研究的基本工具之一,物理学的任何一个定理或者规律,都必须归结为数学表达式才有切实的意义。一、数学概念在物理教学中的实效性应用从事物理教学的教师都有这样的体会,如果问学生带电粒子垂直进人电场在不计重力时会做什么运动,轨迹如何?学生都会回答是与电场方向平行的匀速直线运动和与电场方向垂直的匀加速直线运动的合运动,即类平抛运动,轨迹是一条抛物线,但为什么是抛物线,学生就回答不上来了。如果教师能够把与
Mathematics is one of the basic tools of physics research. Any theorem or law of physics must be reduced to a mathematical expression that has practical significance. First, the effectiveness of mathematical concepts in physics teaching Teachers engaged in physics teaching have this experience, if asked students to enter the electric field perpendicular to the electric field in the absence of any gravity will do what movement, trajectory? Students will answer is the electric field The direction of parallel uniform linear motion and the direction of the electric field perpendicular to the uniform acceleration of linear motion combined movement, that is, class flat throwing motion, the trajectory is a parabola, but why is the parabola, the students can not answer up. If teachers can put together
