When should I use rigidbody and when shouldn't

[justadeveloper]

I’m getting confused with this one, when should and when shouldn’t I use rigidbody?

I suppose that those are to be used whenever you want to apply physics to that object and when it is not static.

Unity - Manual: Rigidbody component reference

You don’t need it when you only need collision on the object (like a static wall).
