dt2 This chapter covered Oscillations. We still need to have a firm grasp on all the past problem- solving techniques from the first 14 chapters. In addition to those past tools and techniques, we are now going to add the following. d2x A) If your FBD boils down to an equation of form: = a = -w2x i) What type of motion do you have? ii) What is the equation of motion that describes the motion? B) In the cases of objects that have small oscillations (i.e. 0 < 10°) i) what approximation do you use to express motion as SHM? ii) What is the approximation called? iii) For SHM motions, give two examples where this approximation must be used. C) In the cased of a damped oscillator, i) What form is the equation of motion going to have? ii) iii) What is t called in the equation of motion? What does “time constant, q” refer to in a damped harmonic oscillator?
