1. This document discusses key concepts related to oscillations and waves including: simple harmonic motion (SHM), parameters that describe SHM like amplitude, period, frequency, phase, and the relationships between displacement, velocity, and acceleration in SHM.
2. Examples of SHM include a mass on a spring and a simple pendulum. The frequency and period of oscillations can be determined from the properties of the object and spring/pendulum.
3. Forced oscillations and resonance are explored where a driving force can excite the natural frequency of an object, causing large oscillations. This can be useful or destructive depending on the situation.
9. Phase This information concentrates on what phase of the cycle is being executed. It is not concerned with the particulars of amplitude. Mathematically, the phase is the "w t" in: x(t) = A cos ( t)
