Simple harmonic motion (2)

Question 1

Frequency

Answer 1

number of oscillations per second.

Question 2

Simple harmonic motion

Answer 2

a repetitive motion about an equilibrium position. The equation that describes this motion is F=-kx.

Question 3

Damped oscillation

Answer 3

a damped oscillation occurs when friction or wind resistance takes energy out of the oscillation.

Question 4

Resonant frequency

Answer 4

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.

Question 5

Resonance

Answer 5

an oscillator undergoes high-amplitude oscillations (resonance) when the driving frequency is the same as the natural frequency.
