Chap 10: Oscillations Flashcards
● Amplitude:
Magnitude of the maximum displacement from its equilibrium position.
● Period:
Time taken for one complete oscillation.
● Frequency:
Number of oscillations per unit time.
● Angular frequency:
Product of the frequency of oscillation and 2π.
● Phase:
State of the oscillation of a body at a particular time.
● Phase difference(btw oscillators and btw oscillations) :
○ Difference in the state of oscillation between two oscillators at a particular instant.
○ Difference in the state of oscillation for one oscillator at two instances in time.
● Simple Harmonic Motion:
motion of a body such that its acceleration is proportional to its displacement from its equilibrium position and its acceleration is always opposite in direction to its displacement from the equilibrium.
● Damping:
The decrease in the amplitude of oscillation with time due to energy loss.
● Forced oscillations:
An oscillatory system driven by an external periodic force
● Resonance:
When the frequency of the driving force equals the natural frequency of the oscillating system. Maximum energy transfer occurs and the amplitude of oscillations of thesystem is at its maximum.
