“向心力”、“向心加速度”是圆周运动中两个重要的物理量,是匀速圆周运动一章的重点内容。在技校多年的物理教学中本人对“向心力”、“向心加速度”概念的正确建立,作了一点粗浅的探讨。 “Centripetal force” and “centripetal acceleration” are two important physical quantities in circular motion, which are the key contents of the chapter of uniform circular motion. In physics teaching for many years in technical schools, I made a brief discussion about the correct establishment of the concept of “centripetal force” and “centripetal acceleration.”
