PHY133 Harmonic Motion PHY133 - Classical Physics I Laboratory Simple Harmonic Motion The phenomenon of simple harmonic motion is studied for masses on springs and suspended pendulums. The physical basis of these oscillations is that the force exerted on a mass is proportional to the negative of the displacement of the mass from equilibrium, i.e. is "restoring". This relationship may be written, F = -m ϖ 2 x , where m is the mass, ϖ is the angular frequency (or velocity), and x is the displacement from equilibrium. Equipment 1. 1 air track with glider/spring oscillator, 2. audio tape, 3. small masses, 4. photogates, 5. magnets, 6. 1 simple pendulum, 7. 1 meter stick pendulum, 8. 1 ring pendulum, 9. 1 force transducer, 10. 1 computer and interface box. Method Throughout this experiment, a system (glider between springs, assorted pendulums) will be displaced from equilibrium and the period T of oscillation will be measured. For the various oscillators, the dependence of the period on amplitude will be assessed. For true, simple harmonic motion, there should
