In a forced oscillation, what is the effect of resonance?
Amplitude decreases
Amplitude increases significantly
Frequency decreases
Phase difference becomes zero
At resonance, the driving frequency matches the natural frequency of the system, leading to a significant increase in amplitude.

Q: In a forced oscillation, what is the effect of resonance?
Solution: At resonance, the driving frequency matches the natural frequency of the system, leading to a significant increase in amplitude.
Steps: 6
Step 1: Understand what forced oscillation means. It is when an external force causes an object to vibrate.
Step 2: Know what resonance is. It happens when the frequency of the external force matches the natural frequency of the object.
Step 3: Recognize that every object has a natural frequency at which it vibrates best.
Step 4: When the driving frequency (the frequency of the external force) matches the natural frequency, the object starts to vibrate more strongly.
Step 5: This matching of frequencies causes the amplitude of the vibrations to increase significantly.
Step 6: In simple terms, at resonance, the object shakes a lot more than it normally would because the external force is perfectly timed with its natural vibrations.
