Simple harmonic motion (2) Flashcards
1
Q
Frequency
A
number of oscillations per second.
2
Q
Simple harmonic motion
A
a repetitive motion about an equilibrium position. The equation that describes this motion is F=-kx.
3
Q
Damped oscillation
A
a damped oscillation occurs when friction or wind resistance takes energy out of the oscillation.
4
Q
Resonant frequency
A
the resonant frequency of a structure (or oscillator) is the same as its natural frequency. When an oscillator is driven or pushed at its natural frequency, the amplitude of the oscillations grows large.
5
Q
Resonance
A
an oscillator undergoes high-amplitude oscillations (resonance) when the driving frequency is the same as the natural frequency.
