Lecture Physics A2: Oscillations - PhD. Pham Tan Thi present the content what is an Oscillation, simple harmonic oscillation/motion, period and frequency, angular frequency, displacement as function of time in SHM, . | Oscillations Pham Tan Thi . Department of Biomedical Engineering Faculty of Applied Science Ho Chi Minh University of Technology What is an Oscillation Any motion that repeats itself Described with reference to an equilibrium position where the net force is zero and a restoring force which acts to return object to equilibrium Characterize by - Periodic T or frequency f or angular frequency ω - Amplitude A Model for periodic motion.
