Oscillation Concepts and Terminology

The video tutorial introduces oscillations, defining them as repetitive movements around a fixed point, known as the equilibrium position. It explains key concepts such as displacement, amplitude, period, frequency, phase, and angular frequency. Displacement is the distance from the equilibrium, with amplitude as the maximum displacement. The period is the time for one oscillation, while frequency is the number of oscillations per second. Phase is the cycle fraction completed, measured in radians. Angular frequency is the phase change rate per unit time, calculated as 2π divided by the period.
