Damped Oscillations: Does Time Change?

Click For Summary
In damped oscillations, the time for one complete oscillation remains constant, provided that the damping coefficient (γ) and the natural frequency (ω0) are time-independent. The differential equation governing damped oscillations confirms this, as the relationship between angular frequency and the period does not change over time. Therefore, the period of oscillation is not affected by the damping process itself. This conclusion is derived from solving the relevant equations. Overall, the period remains independent of time during damped oscillations.

The Attempt at a Solution

Hi amit25. The differential equation for damped oscillations is:
\ddot{x}+\gamma\dot{x}+\omega_0^2x=0​
If you solve for the angular frequency of this system and substitute a relationship between the angular frequency and the period of one oscillation. Is this relationship time dependent or independent? That should give you your answer.
 
so time is independent

The period for one oscillation is independent of the time (as long as γ and ω0 are time independent) if you work out an equation for it.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
