です can be used in a lot of different ways. We can also make it into a negative, past tense, and past negative.
From there, we can make many different sentences!
So let's start with a sentence we know.
これはりんごです。This is an apple.
If we want to say 'This was an apple,' all we have to do is change です to でした。
これはりんごでした。This was an apple.
Now how about the negative? What happens if it's not an apple? Then we use ではありません。
これはりんごではありません。This is not an apple.
Finally, if we want to say 'This wasn't an apple.' (Don't know why you'd need it but...)
If you are ever looking at a strange object, red or green, and apple shaped, but you are still questioning they authenticity of it, then you can say これはりんごでしょう。This would probably be an apple.
So this is what I know about です. There is a lot you can do with this knowledge :) If you add か to these then you can turn them into questions.
これはりんごでしたか？Was this an apple?
