补充资料：机械能守恒定律
| 机械能守恒定律 mechanical energy，law of conservation of 动力学中的基本定律，即任何物体系统如无外力作功或外力作功之和为零，系统内又只有保守力（见势能）作功时，则系统的机械能（动能与势能之和）保持不变。外力作功为零，表明没有从外界输入机械功；只有保守力作功，即只有动能和势能的转换，而无机械能转换为其他能，符合这两条件的机械能守恒对一切惯性参考系都成立。这个定律的简化说法为：质点（或质点系）在势场中运动时，其功能和势能的和保持不变；或称物体在重力场中运动时动能和势能之和不变。这一说法隐含可以忽略不计产生势力场的物体（如地球）的动能的变化。这只能在一些特殊的惯性参考系如地球参考系中才成立。 |
