平衡状态是物体运动的一种特殊状态,是我们求解许多力学问题的切入点和突破口,因此正确理解平衡状态至关重要.笔者近期听了一节“力的平衡”研讨课,对上课教师给出的“平衡状态的定义”不敢苟同,现与各位同仁交流,以期抛砖引玉.这位教师说:什么是平衡状态呢?平衡状态指的是物体保持静止或做匀速直线运动. Balancing state is a special state of object motion, which is the starting point and breakthrough of our solution to many mechanical problems, so it is very important to correctly understand the balance state.I recently listened to a section of “balance of power” seminar, Teacher gives “balance of state definition ” disagree, now with my colleagues to exchange, with a view to start a discussion .This teacher said: What is the balance? Balancing refers to the object is still stationary or do a uniform linear motion.
