Focus questions on exam are in Bold Face . Formulas 1. Simple Pendulum ( F T = " mg sin # $ " mg # ): % = g L , T = 2 & L g T = 2 & % f = 1 T = % 2 & , % = 2 & f 2. Physical Pendulum: T = 2 & I mgd (d is distance from pivot to CM point) 3. Damped Oscillator ( F D = " bv ): x = Ae " ( b /2 m ) t cos( % ' t + ) % ' = k m " b 2 m ( ) * + ,- 2 4. Forced Oscillator -Resonance : Resonance Frequency % = k m for mass-spring system 5. Transverse Traveling Waves: y = A cos( kx " % t ) Angular Wave Number : k Angular Frequency: % Wavelength: . = 2 & k Period: T = 2 & % Wave Speed of Propagation: v = % k = . T = f ....
