圆锥曲线是高中数学的重要内容,与物理竞赛联系密切:圆锥曲线具有显著的光学特征;运动物体的轨迹往往是椭圆、双曲线、抛物线.圆锥曲线与物理知识的综合应用,可以提高学生学习兴趣,提升学生的科学素养.一、椭圆知识的运用 Conical curve is an important content of high school mathematics, and is closely related to the physics competition: Conical curve has significant optical characteristics; the trajectory of the moving object is often an elliptical, hyperbolic, parabolic, conical curve and physics knowledge, which can improve the students’ interest in learning. , to enhance the students’ scientific literacy. First, the use of elliptical knowledge
