Wynn Dixon PHYS 1240-020 Post Lab Conservation of Angular Momentum 1. The slope of the graph represents the quantity of final moment of inertia of the system divided by the initial moment of inertia of the system. 2. Slope = I f I i I f = I D + I C I i = I D Slope = I D + I C I D I c = I D ( slope 1 ) 3. We measured the point mass from the center point. Since the rotational axis is in the middle of the bar, the radius is the distance from the axis outward. 4. Although the stop-screws do have mass, their moment of inertia is so small it can be ignored

Rotational kinetic energy is found by using K = 1 2 I ω 2 For kinetic energy to be conserved, the initial kinetic energy must be the same as the final kinetic energy. Using the values of I i , I f , ω i , and ω f in each exercise, the kinetic energies were calculated, and the values are different. Therefore, kinetic energy is not conserved in either exercise of the experiment....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
