Question

what is meant by forced oscillations?​

Answer 1

Answer:

Oscillations produced by an external periodic driving force (with a frequency that's not the natural frequency) are called forced oscillations. There is an increase in the amplitude of oscillations when the driving force is close to natural frequency of the system.

Answer 2

Answer:

HERE IS your ansWer dear and yes DO MRK BRAiNLIESt

Explanation:

Oscillations produced by an external periodic driving force (with a frequency that's not the natural frequency) are called forced oscillations. There is an increase in the amplitude of oscillations when the driving force is close to natural frequency of the system.

If it oscillates with its natural frequency, the motion will die out. A good example of forced oscillations is when a child uses his feet to move the swing or when someone else pushes the swing to maintain the oscillations.
