Summary:
Oscillations refer to repetitive back-and-forth movements around a
central equilibrium position. They are prevalent in various natural and
artificial systems, including pendulums, springs, waves, and even
atoms. Understanding oscillations is crucial in fields like mechanics,
electronics, and wave phenomena.
Key Points:
Equilibrium Position: The central point around which an oscillating
system moves.
Amplitude (A): The maximum displacement from the equilibrium
position.
Frequency (f): The number of complete oscillations per unit time
(usually measured in Hertz, Hz).
Period (T): The time taken for one complete oscillation (T = 1/f).
Angular Frequency (ω): The rate of change of phase with time (ω =
2πf).
Simple Harmonic Motion (SHM): Oscillatory motion where the
restoring force is proportional to the displacement from equilibrium (F
= -kx).
Damped Oscillations: Oscillations with decreasing amplitude due to
dissipative forces like friction.
