71) Theoretically, how does the radial force exerted on an object vary with the radius of its circular path 3 when it is revolving: (a) at constant frequency? (b) with constant speed? Is this theory supported by your experimental results? Write out your answer in a clear and well supported paragraph. 9 0 erase this and type in your answer 2) When the value of the revolving mass and the radius of its path are both held constant, what theoretical effect on the period does increasing the radial force have? Did you observe this experimentally? Write out your answer in a clear and well supported paragraph. erase this and type in your answer 3) When you change the revolving mass (while keeping the path radius and radial force constant), what is the theoretical effect on its period? Did you observe this experimentally? Write out your answer in a clear and well supported paragraph. erase this and type in your answer 4) Does the centripetal force acting on an object in uniform circular motion do work on the object? Why or why not? In this experiment, what force does work on the bob to cause ir to slow down and eventually stop once you stop applying a rotational force with your fingers? erase this and type in your answer
