Description
🎯SAMPLE LEARNING GOALS :
•Explain what a normal mode is.
•Define the frequency, amplitude, and phase of a normal mode.
•Explain why different normal modes have different frequencies and why higher-numbered modes have higher frequencies.
•Identify how many normal modes a given system has.
•Sketch the individual modes qualitatively for both 1D and 2D systems.
•Explain the distinction between transverse and longitudinal normal modes in a 1D system.
•Explain how adjusting the phase of a normal mode affects the motion of the system.
•Explain qualitatively how any arbitrary state of the system can be written as a sum of normal modes; that is, explain the superposition principle.
•Explain which properties of the system are set by the initial conditions, which properties are time-independent, and which properties are time-dependent.
•Explain why striking a metal plate in one spot raises the temperature of the plate.
