摘要
基于自然坐标下曲线运动的全加速度方程,设计了圆周运动加速度综合演示仪.该演示仪通过手动、电动及制动可分别演示圆周运动中切向加速度(包括正负加速度)和法向加速度,还可以直观地观察到圆周半径对切向和法向加速度的影响,角速度对法向加速度的影响及角加速度对切向加速度的影响.
Based on the total acceleration equation of curvilinear motion under natural coordinates,a demonstration instrument for acceleration of circular motion was designed to demonstrate tangential acceleration(including deacceleration)and normal acceleration,respectively.Not only the effects of curvature radius on both tangential and normal acceleration,but also the effects of angular velocity on normal acceleration and angular acceleration on tangential acceleration were observed directly.
