You perform an investigation to determine how the frequency of a rubber stopper in a uniform circular motion in the horizontal plane depends on the magnitude of the tension force acting on the stopper, the mass of the stopper, and the radius of the circle.
(a) Sketch these graphs to show the relationships.
(b) You are then asked to sketch the corresponding graphs by replacing the frequency with the period of revolution as the dependent variable. Sketch these graphs.
(c) When an object is kept in a circular motion in the vertical plane by a tension force, the tension needed is greater at the bottom of the circle than at the top. Explain in your own words why this is so.
