针对传统探究向心力 F大小与质量m、角速度ω和半径r之间关系的实验存在的不足，重新设计了实验装置，该实验装置利用PASCO力传感器测向心力的大小，用调速电机来改变金属小球作圆周运动的角速度，并用霍尔传感器测量电机的转速，而金属小球的质量和小球的旋转半径则可以定量改变，由此可定量探究向心力的大小 F与质量m、角速度ω和半径r之间的关系。

A device was designed to overcome the shortages of the experiment to explore the effects of mass ,angular velocity and radius on centripetal force .The device used PASCO force sensor to measure the centripetal force ,variable speed motors to change the angular velocity of the metal ball ,and Hall sensors to measure the rotation speed of motor ,by changing the mass of the metal ball or rotation radius ,the relationships of centripetal force ,mass ,angular velocity and radius were quan‐titatively obtained .
