Yes they are same as Inheritance in the means to achieve Polymorphism.

An ideal instance of using Inheritance would be when you want to create an entirely new class, but wish to borrow a group of existing attributes or methods resident in an existing Abstract or super Class, instead of re-inventing the wheel. If you had an Abstract Class Carnivore and wanted to create a subclass Cat, you could instantly inherit all the methods that were common in Carnivore that applied to Cat without writing new code.

Polymorphism could be best applied when you had an existing SubClass that you wanted to modify or add a feature that could borrow a method that existed in a higher class. Take the Cat subclass, which inherited attributes from Carnivore, and you wanted to add the method Stalk, which would generically describe how a carnivore approaches its prey. However its implementation in Cat would detail the stealth it uses that are unique to a Cat.
