Formulas

1. Core Concepts

Natural frequency = definite frequency of oscillation of a body when displaced from equilibrium and left free

A force whose magnitude and direction change periodically with time is called a periodic force

2. Damped Oscillations

Amplitude decreases with time due to energy dissipation

Energy dissipated = energy converted into heat

3. Forced Oscillations

Forced oscillations occur when the body oscillates with the frequency of the external force

Amplitude of forced oscillations is usually small when driving frequency differs from natural frequency

4. Melde's Experiment

One complete cycle of alternating current produces one vibration of the rod

Stationary waves are produced by superposition of direct and reflected waves
