It depends. If you are saying "it is" then yes. Example: It's black. You're saying "It is black." An example of where it would not need an apostrophe would be like, "Its friends were weird."Additional answerNot only does it not need one, it mustn't have one!)
No. Possessive pronouns don't take apostrophes.
When you are talking about the two Robinsons, Megan and Travis, the s serves to indicate that the noun is plural, therefore it does not need an apostrophe. You would only need an apostrophe to indicate the possessive form of the word, as in, that is Mr. Robinson's car.
If you are saying: - your e.g. your phone, then no. - you're e.g. you're pretty, then yes because it replaces the 'a' from the are.
I am does not need an apostrophe. It is only when you make it into a contraction by dropping the a that you need the apostrophe. It becomes I'm in that situation.
