在我们学习高中物理与重力相关的内容当中,有很多的试题是和物体的重心变化有关系的。同学们如果能正确掌握物体的重心变化,利用其与重力做功以及重力势能变化之间的关系,对物理的解题规律灵活运用,这样我们在解决题目时往往能够事半功倍。 Among the things we learned about high school physics and gravity, there are a lot of questions that are related to the change in the center of gravity of objects. If students can correctly grasp the change of the center of gravity of an object, use its relationship with gravity work and the change of gravity potential energy, and use the physics problem-solving rule flexibly, so that we can often do more with less when solving problems.
