Question

What is a future tense? What are its uses? 

Answer 1

It is a tense which is used to express future in English, to be precise - ideas and decisions about future which are made ad hoc and can't yet be validated (Future Simple), decision which you are sure about but you haven't yet made any preparations for (~going to) and those you had already prepared for (present continuous).

Formation: 

Present Simple - [subject] + will + [predicate]  e.g. I will go
~going to - [subject] + am/are + going to [predicate] e.g. I am going to go
Present Continuous - [subject] + am/are + [gerund form of a predicate] e.g. I am going

Answer 2

Here you go...

The simple future is a verb tense that’s used to talk about things that haven’t happened yet.

Example: This year, Jen will read War and Peace. It will be hard, but she’s determined to do it.
