146 Chapt. 16 Oscillations and Simple Harmonic Motion 5. Frequency (i.e., cycles per unit time) is give by: a) f = P = ω . b) f = 1 /P 2 = ω/ (2 π ) 2 . c) f = 1 /P = ω/ (2 π ). d) f = 1 /P = (2 π ) /P 2 . e) f = P = ω/ (2 π ). 016 qmult 00300 1 1 1 easy memory: SHO equation 6. The simple harmonic oscillator (of mass m ) in one dimension is a system in which Newton’s 2nd law gives the equation: a) ma = − kx . b) ma = kx . c) m/a = k/x . d) m/a = − k/x . e) F = − kx . 016 qmult 00320 1 1 4 easy memory: SHO solution 7. A solution to Newton’s 2nd law for the simple harmonic oscillator is simple harmonic motion— which is a melodious, uncomplicated motion. The solutions for displacement, velocity, and acceleration for a case when the motion of the oscillating objects starts at time t = 0 at its maximum displacement A are, respectively: a) x = A sin( ωt ); v = ωA cos( ωt ); x = − ω 2 A sin( ωt ). b)
