Abstract
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 quantitatively obtained.
