Unformatted text preview: that the string between the pulley and rotating mass is horizontal. 6. To find the empirical value of the rotating mass from the slope of the graph I would manipulate the magnitude of the net force equation to the axis for the graph 2 vs. F. Our new equation reads with the slope of the graph being so to calculate the rotational mass, multiply the slope by the measured radius, and then take the reciprocal of this value. 7. I expect the yintercept to be zero for the graph because when the Force of the object is zero, the angular speed is also zero because any value multiplied by zero equals zero. =. Therefore the yintercept has to be zero when x equals zero....
