论文摘要
学生对瞬时速度的概念遇到的困难是众所周知的。这部分是由于瞬时速度通常是根据数学限制的概念来定义的，这对于许多入门物理课程中的学生来说可能尚不清楚。在这项工作中，我们提出了一项互补的教学建议，可以帮助学生更好地掌握瞬时速度。该方法基于伽利略对瞬时速度的观念，在开发了无限微积分之前，他从梅尔顿学者那里借来了。
Difficulties presented by students on the concept of instantaneous velocity are well known. This is in part due to instantaneous speed being often defined in terms of the notion of mathematical limit, which may not be clear to many students in introductory physics courses. In this work we present a complementary teaching proposal that can help students to get a better grasp of instantaneous velocity. The approach is based on Galileo's ideas on instantaneous speed, which he borrowed from the Mertonian scholars much before infinitesimal calculus was developed.
