5.2 Damping and Resonance

The greatest distance an object moves from equilibrium position during SHM

• Displacement
• Amplitude
• Height
• Zenith

Motion when a varying force is used to drive an oscillating system

• Reverberation
• Over damping
• Forced oscillation
• Natural frequency

Repeated over and over again at regular intervals

• constant
• cyclical
• periodic
• rhythmic

A guitar string is plucked and set into oscillation. Over time the amplitude of oscillation of the string decreases. The oscillation of the string is said to be ...

• damped

• forced

• natural

• resonant

When a forced oscillation is damped, the amplitude

• builds up quite slowly

• constantly rises and falls

• is always small

• is reduced

What occurs when vibrations traveling through an object match the object's natural frequency?

• reflection
• diffraction
• resonance
• refraction
