Unformatted text preview: Phys 211 4/20/09 Chapter 15 Oscillations Oscillations Describe displacement , velocity , acceleration Back-and-forth motion Consider kinetic and potential energy Oscillators: Simple Harmonic Oscillator (SHO) Damped Oscillator Forced Oscillations, Resonance Examples: spring-mass system, simple pendulum, physical pendulum, torsional pendulum Simple Harmonic Motion (SHM) Displacement Displacement is periodic (changes as a function of time) Periodic Function Amplitude- x m- extremum of wave motion Period- T - time to complete one cycle of motion Phase- offset of one curve to another (or from origin) These waves have the same period, are in-phase. They have different amplitudes. These waves have the same amplitude. They are in- phase (phase angle=0 deg) as the origin and completely out of phase (phase angle=180 deg) after T`. Angular Frequency x ( t ) = x m cos( t + ) x ( t ) = x m cos( t ) x ( t + T ) = x m cos( ( t + T )) x ( t ) = x ( t + T ) ( t + T ) = t + 2 t +...
