Part I: Centripetal force from the rotational motion
... The purpose of this experiment is to calculate the centripetal force needed to keep an object in uniform circular path. We accomplish that in two ways; by finding the weight needed to stretch a rotating mass until it reaches a sensitive probe and also by allowing this mass to rotate at a speed neces ...
