Lab Manual Lab 9: Simple Harmonic Oscillation Before the lab, read the theory in Sections 1-3 and answer questions on Pre-lab Submit your Pre-lab at the beginning of the lab. During the lab, read Section 4 and follow the procedure to do the experiment You will record data sets, perform analyses, answer questions, and have Check Boxes checked on Report Sheets, Submit your Report Sheets before you leave the lab. 1. Introduction Oscilations, or periodic motions, are motions that repeat themselves. What many types of os- cillations have in common is a restoring force that continually pushes the system back to arn equilibrium point. Under ideal conditions, the total mechanical energy is conserved for such sys- tems, meaning the energy gets converted back and forth between potential and kinetic. We will first examine periodic motion by observing a spring acting as a simple oscillator. This will introduce the concept of oscillatory motion about an equilibrium point described by its an- gular frequency w. It will also be an introduction to sinusoidal equations of motion as solutions of differential equations that govern oscillating systems. Different realizations of periodic mo- tion will be explored via a rod pendulum. 2. Key Concepts Simple harmonic motion Hook's law .Simple pendulums Amplitude and frequency of oscillation .Elastic potential energy Energy conservation 3. Theory 3.1 Simple harmonic oscillation Many systems in nature are well approximated by the idealization of simple harmonic oscilla- tion. The word "simple" here refers to the fact that there is only one mode of oscillatory motion rather than a combination of multiple oscillations or oscillators. The harmonic" aspect de- scribes a restoring force that is proportional to the displacement, and the mass undergoes end- less periodic motion at a single frequency We first look at an oscillating spring with a mass m at its end, as shown in Figure 1. Hooke's law says that the elastic force acting on the mass is
