求曲线曲率的问题常出现在高中物理竞赛中,而近年来高考中也涉及到曲线曲率的问题,例如2008年江苏理综第14题涉及到曲率半径,2011年高考安徽理综第17题更是要求求出曲线曲率.在数学中曲线的曲率半径可以用高等数学的方法求出.这里我们另辟蹊径,从物理学的角 For curvilinear curvature problems often appear in the high school physics competition, and in recent years the college entrance examination also involves the issue of curve curvature, for example, Jiangsu Science and Technology in 2008 No. 14 relates to the radius of curvature, Is required to find the curvature of the curve in mathematics the radius of curvature of the curve can be used to find higher mathematics here we find another way from the angle of physics
