公元前４世纪，以亚里士多德为代表的学者们认为重的物体一定比轻的物体下落得快，这种观点在近两千年里一直被人们奉为真理，直到１７世纪才由伟大的物理学家伽俐略所推翻。在今天的科学课堂上，教师讲授这一知识采取的策略往往是先提出问题：重的物体与轻的物体哪个下落得快 In the 4th century BC, scholars represented by Aristotle believed that heavy objects must have fallen faster than light objects. This view has been regarded as truth for nearly two thousand years until the 17th century. The physicist Galerino was overthrown. In today’s science classrooms, the teacher’s strategy for teaching this knowledge is often to ask the question first: which of the heavy objects and light objects falls quickly?
