PHY 104 Oscillatory Motion Objective Question
Take CBT

Question

Eventually, after the 'transient effect' dies away in a forced oscillation, the body:
Options
A Stops oscillating.
B Oscillates at its natural frequency with increasing amplitude.
C Oscillates with constant amplitude and phase, and with the frequency of the applied force.
Correct Answer
D Oscillates with decreasing amplitude at the natural frequency.
Correct Answer

Option C is the correct answer.

Detailed Explanation

On page 23, the text states: 'Eventually, the body yields to the external force and oscillates with constant amplitude and phase, and with the frequency of the applied force.' These are called 'forced oscillations'.

Hint

In the long term, the driving force dictates the oscillation frequency.
