Lecture #6 Terminology Flashcards
What expression determines the three regimes for an oscillator?
w0^2 - gamma^2
Quality of an oscillator
Measures the # of times an underdamped oscillator oscillates before dying
A linear drag force is sufficient to describe
Gently-moving systems
Gamma is
The damping factor
w0
The natural/angular frequency
Natural/angular frequency
The frequency without damping
Condition for underdamped
gamma squared < w0^2
Condition for overdamped
gamma squared > w0^2
Condition for critical damping
gamma squared = w0^2
For an LC circuit, what is w0^2 equal to?
1/(LC)
Which type of damping gets to rest the fastest?
Critically damped oscillator
In most cases, what can you say about T0 and Td for an underdamped oscillator?
T0 and Td are approximately equal (if the quality is high enough)
