Obviously, you would like to find out whether the hull has an intrinsic. So, this becomes an intrinsic characteristic of the hull, because intrinsically you have designed the hull. So, that if there is a disturbance, there it takes the straight line, know I give many examples for that, you take a pen or any any object, you through on the on the, you throw on an ear, what happens I will come back to this diagram.
I have this something object I throw on the ear. What is the trajectory text, you can throw and find out it may actually go like that. It does not follow a straight line right. See, if I just take a stick, I just some small some pencil and throw it in ear does it follow a perfect path like that. No, but now you put a mass here, and you put a feather here, like in an arrow. What happens, it goes exactly in a perfect line, and you understand that.
