oscillations Flashcards
1
Q
Amplitude definition
oscillations
A
magnitude of the maximum displacement from its equilibrium position
2
Q
Period definition
oscillations
A
time taken for one complete oscillation
3
Q
Frequency definition
oscillations
A
number of oscillations per unit time
4
Q
Angular Frequency definitIon
oscillations
A
product of the frequency of oscillation & 2 pi
5
Q
Phase definition
oscillations
A
state of oscillation of a body at a particular time
6
Q
Phase Difference definition
oscillations
A
- 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
(use the correct definition based on the context)
7
Q
Simple Harmonic Motion
oscillations
A
- motion of a body such that its acceleration is proportional to its displacement from its equilibrium position
- its acceleration is always opposite in direction to its displacement from the equilibrium
8
Q
Damping definition
oscillations
A
the decrease in the amplitude of oscillation with time due to energy loss
9
Q
Forced Oscillations definitions
oscillations
A
- the application of a periodic driving force to a system to make it oscillate at the frequency of the applied force rather than its natural frequency
- the driving force provides a constant forcing (driving) frequency and a constant amplitude
10
Q
Resonance definition
oscillations
A
- the frequency of the driving force equals the natural frequency of the oscillating system
- maximum energy transfer occurs
- the amplitude of oscillations of the system is at its maximum
