In the image is a stopper attached to a fishing line that is threaded theough a glass rod. Hanging from the end of the line opposite the stopper is a 100-gram mass. The stopper is being whirled in a horizontal circle, first quickly, then decreasing to a slower speed. a. True or false: the only outward forces are the force of the stopper pulling on the string, and the string pulling on the glass rod. b. Does there appear to be a relationship between the speed and the force needed to keep the stopper moving in a circular path? If so, what kind of relationship do you expect? As the speed increases, does the force needed increase or decrease? Is this some type of direct relationship or an inverse relationship? c. Does there appear to be a relationship between the radius of the circulat motion and the force needed to keep the stopper moving in a circular path? If so, what kind of relationship do you expect? As the radius increases, does the force needed incrase or decrease? Is this some type of direct relationship or an inverse relationship?
