EF 152 – Physics for Engineers Spring, 2009 Recitation 3.2 Harmonic Motion and Pendulums Task 1. The favorite – Concept Questions. First we will work concept questions with harmonic motion. A mass on a spring in simple harmonic motion has amplitude A and period T. 1. What is the total distance traveled by the mass after a time interval T? a. 0 b. A/2 c. A d. 2A e. 4A 2. At what point is the acceleration zero? a. Point 1 b. Point 2 c. Point 3 3. At what point is the velocity zero? a. Point 1 b. Point 2 c. Point 3 4. If the amplitude of a simple harmonic oscillator is doubled, which of the following quantities will change the most? a. frequency b. period c. maximum speed d. maximum acceleration e. total mechanical energy 5. A mass is suspended from the ceiling of an elevator by a spring. When the elevator is at rest, the period is T. What happens to the period when the elevator is accelerating upward? a.
