this article comes from the network, which has great influence and reputation in the country. However, this "maximum" refers to the maximum acceleration of the object in the deceleration process, not the maximum in the whole process. Therefore, based on the above analysis alone, it is impossible to draw the conclusion that the acceleration is the maximum at the lowest point.
