从2016 年诺贝尔物理奖及费曼物理教育思想受到启发，本文讨论了目前大学物理教学所欠缺的方面: 溯本求源和结果推广.以阿特武德机、抛体轨迹、斜面上的非惯性系、桌面上的绳子为例，从简单模型悟出质点动力学的几个要点: 对约束方程求导获得变量之间关系; 弹道曲线的理想化和无量纲化; 非惯性中的等效重力; 逆向思维判断系统运动趋势等.

Illumined by 2016’s Nobel prize and Feynman s physical education，we discuss deficient for the moment of college physics，i.e.， searching origin and generalization of result.Several key points are summarized from the Atwood machine， trajectory of throwing body，non-inertial system on the tilted surface，a coed on a stable as examples.Namely，the relation between a few variables through derivation of the restrict equation is found; idealization and dimensionless of the trajectory curve; effective gravity force in the non-inertial system; the motion tendency of a system is judged by using the reversal thinking.
