Mass-spring system Simple Pendulum system Period, T Frequency, f Equilibrium position Displacement, x Amplitude, A Acceleration, a Damped Oscillation Forced Oscillation Resonance of SHM Velocity, v Energy of SHM Chapter 8 Oscillations What is Oscillation/SHM? Definition General properties of SHM SHM applied on IDEAL physical system SHM applied on REAL physical system PPH0075 Physics 1 Chapter 8 ______________________________________________________________________________________ ASD2008/09 2/ 12 8.1 OBJECTIVES At the end of this chapter, students should be able to: a. Explain what is meant by Simple Harmonic Motion. b. Understand and use the terms amplitude, period, frequency, angular frequency and phase difference and express the period in terms of both frequency and angular frequency for both mass-spring system and simple pendulum. c. Describe phase lead, phase lag, antiphase and inphase. d. Describe the interchange between kinetic and potential energy during simple harmonic motion. e. Explain what is a resonance and give example. 8.2 TYPES OF MOTION a. Motion in which a body moves from one place to another with respect to time, e.g a moving train. b. Motion in which a body moves about a fixed point, back and forth over the same path, e.g the bob of a simple pendulum. This type of motion is called oscillatory motion. 8.3 DEFINITION OF SOME TERMS a. Periodic Motion This is when motion takes place at equal intervals of time; eg, planetary motion, simple pendulum motion, etc. b. Period ( T ) Time taken for one complete oscillation. c. Frequency ( f ) Number of oscillations per second. It is measured in hertz (Hz) Frequency and period are related to each other by f = 1 / T ....
