Conservative Forces and Potential Energy

Core Sentence / 核心句

A conservative interaction has path-independent work and can be represented by potential energy.

\qquad F_x=-\frac{dU}{dx}$$ 常见例子：gravity、ideal spring force、electrostatic force。 ## Watch Out / 易错点 potential energy 属于 interacting system；零点可选，但能量差和物理预测不变。 ## Mentioned In / 出现位置 - [[AP物理C力学第6次正课-功功率势能与机械能守恒#5.
