What’s the difference between a free oscillation and a forced oscillation?

Are you aware that a forced oscillation oscillates at the driver frequency! It takes some time for the driver and drivee to “settle down”. When we talk about the amplitude of the forced oscillation, we are referring to the final steady-state amplitude.

How does the driving frequency determine the amplitude of the forced oscillation?
