Physical Pendulum Max Stevens Luke Corbin 1/30/2019 ABSTRACT: The purpose of this lab is to explore simple harmonic motion, oscillations, and, more specifically, the physical pendulum. INTRODUCTION: An oscillation is a motion that repeats itself over a regular cycle. The oscillation of a physical object involves a restoring force, which forces the object towards equilibrium. The momentum of the object causes it to move past equilibrium and encounter another restoring force, and the process repeats, exhibiting an oscillatory motion. The physical pendulum consists of a rigid object swinging, or oscillating, back and forth on an axis of rotation that is offset from its center of gravity. The pendulum oscillates because gravity pulls the pendulum down around a fixed axis of rotation. Once the pendulum reaches the bottom of a swing, it’s momentum carries it past the bottom of the swing and upwards, until it’s kinetic energy is diminished and overcome by the force of gravity, and the process repeats. Simple harmonic motion is an oscillation where the restoring force is proportional to the displacement. Provided that there is little friction at the axis of rotation and the oscillation is over small angles, the simple pendulum is an example of simple harmonic motion.

THEORY: In this lab, the period of the oscillations of a rigid body pendulum must be found. In order to do this 2 π is divided by ω . ω is the square root of force times distance to the axis of rotation divided by the moment of inertia to that axis of rotation. These calculations are accurate with an angle of rotation less than 15 . Combining those the following equation is used: T = 2 π

    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.
