DO NOT POST ONLINE @ 2019 Chapter 12 Review | 1 Chapter 12 Review: Oscillations Section 12-1: We live in a world of oscillations Concept Check 1. Explain how a force can cause oscillatory motion. Section 12-2: Oscillations are caused by the interplay between a restoring force and inertia Concept Check 1. What is the difference between period and frequency? What are the units of period and frequency? 2. What are the units for angular frequency? If you are observing an oscillator (an object on a spring or a pendulum), which quantity would you naturally measure: frequency or angular frequency? Problem-Solving Review 1. A child on a swing goes back and forth three times every 4.0 s. (a) What is the frequency of this motion? (b) What is the period of this motion?
