object- instance of class
class - Blueprint of object
Encapsulation - defining different methods inside a class and calling them as per our
requirement. It also protects our data.
Polymorphism - Different behavior in different instances
Abstraction - Hiding our irrelevant Data
Inheritance - inheriting properties of a parent or superclass/ classes to a child or subclass/classes as per our requirements(One property of the object is acquiring another property of an object)

Good keep it up 
We can slightly improve the definition for encapsulation and inheritance as:
Encapsulation: defining different methods inside a class and calling them as per our requirement. It’s also protect our dat.
Inheritance: inheriting properties of parent or super class/ classes to child or sub class/classes as per our requirements.
