AP Physics - Oscillations Practice Test Multiple Choice Identify the choice that best completes the statement or answers the question. 1 A body oscillates with simple harmonic motion along the x -axis. Its displacement varies with time according to the equation x = 5.0 sin ( p t ). The acceleration (in m/s 2 ) of the body at t = 1.0 s is approximately a. 3.5 b. 49 c. 14 d. 43 e. 4.3 2 The amplitude of a system moving with simple harmonic motion is doubled. The total energy will then be a. 4 times larger b. 3 times larger c. 2 times larger d. the same as it was e. half as much 3 A uniform rod (mass m = 1.0 kg and length L = 2.0 m) pivoted at one end oscillates in a vertical plane as shown below. The period of oscillation (in s) is approximately a. 4.0 b. 1.6 c. 3.2 d. 2.3 e. 2.0 4 The figure shows a uniform rod (length L = 1.0 m, mass = 2.0 kg) suspended from a pivot a distance d = 0.25 m above its center of mass. The angular frequency (in rad/s) for small oscillations is approximately a. 1.0 b. 2.5 c. 1.5 d. 4.1 e. 3.5 5
