| 摘 要： | 本文就静摩擦力做功以及在静摩擦力做功过程中机械能守恒问题，结合实例做进一步讨论。从而得出系统内静摩擦力做所做的功不会引起本系统机械能的变化，静摩擦力做功的过程。只能使系统内的机械能之间相互转化或在物体之间传递机械能。

| 关 键 词： | 静摩擦力 功 动能 机械能守恒 |

| Abstract: | A discussion is made of the work done by static frictional force and the conservation of mechanical energy in the work doing process by way of typical cases. It is concluded that the work done by static frictional force in a system does not lead to the change of mechanical energy of the system, which is found , instead, to undergo an inter - conversion or transfer between bodies. |

| Keywords: | static frictional force work kinetic energy conservation of mechanical energy |
