在新编高中物理课本(甲种本)第一册第65页上写到“伽利略是首先认真研究变速运动的物理学家。伽利略就是从最简单的变速运动着手的。他设想,最简单的变速运动的速度应该是均匀变化的。但是,速度的变化怎样才算均匀呢?他考虑了两种可能:一种是速度的变化对时间来说是均匀的,即经过相等时间,速度变化相等;另一种是速度的变化对路程来说是均匀的,即经过相等的路程,速度的变化相等。伽利略断定第一种方式最为简单,并证明这种运动方式在自然界中是的确存在的。” 对第一种运动方式,我们都很熟悉了。速
Writing on the 65th page of the first volume of the new high school physics textbook (A copybook), Galileo is the physicist who first carefully studied the variable speed movement. Galileo started from the simplest variable speed movement. He imagined that the easiest. The speed of the variable speed movement should be uniform, but how does the speed change be even?He considered two possibilities: one is that the speed change is uniform with time, that is, after an equal time, the speed changes Equally; the other is that the speed change is uniform for the distance, that is, equal distance, equal speed change. Galileo concludes that the first method is the simplest, and proves that this method of movement does exist in nature. "We are all familiar with the first form of exercise. speed
