Mechanical Waves

[AFEmp]

For mechanical waves will we need to understand dampening oscillations (in which resistive forces decrease the mechanical energy) or forced oscillations (in which one applies an external force to compensate for energy lost from a resistive force)?

I don't think we do, but I would hate to skip over it.

It's not on there. So no. You might get a passage on it, but you don't have to know the details that's not in the passage to answer the questions.

The only thing I would keep in mind is that naturally dampening oscillations will have their amplitudes decreasing exponentially.

but i'm sure they could expect you to know how a pendulum or spring behaves if air resistance is not negligible, in which case it would then be a dampened pendulum or spring.
