Modeling Behavior with Protocols Question

In this video, Pasan explains that when you have two classes that are similar with similar method implementations, a protocol is the best solution for achieving this elegantly. That makes sense. However, some additional research has led me to discover polymorphism and it sounds like that is also a preferred approach, whereas you could simply use the base class to model the functionality and update these methods in the subclasses.

So, I have two questions. First, is my understanding of polymorphism correct? I am still rather new to all of these concepts. Second, do protocols trump polymorphism and when would you use one over the other?

Thanks!
