摘要: 引入急动度和猝变动力学等新概念。用以充实大学物理教学内容,是一种正在形成的趋势.本文提供了一个关于猝变动力学新概念教学的初步框架。

关键词: 猝变动力学, 急动度, 史瓦兹定理, 力变率, 猝量, 加速度能量, 三阶拉格朗日方程

Abstract: It is a tendency that the new concepts of jerk and jerky dynamics become a part of course of the university physics. A elementary teaching frame of the new concepts on jerky dynamics is constructed.

Key words: jerky dynamics, jerk, Schwarz's theorem, time rate of change of force, jumpulse, energy of acceleration, three-order Lagrangian equation
