how should I make a realistic arrow rotation arc 2D?

Hello, I have a bow that shoots well, it is 2D, can shoot in all 8 directions. it fires well, the arrow it a trigger and rigidbody, BUT the arrows rotation is always the same as it was when it first fired and I don’t know this advanced of math, I need to know some sort of formula or something that I can tweak to make the arrow pretty much point to where it will be in the next frame all the way until it hits the floor(where it gets deleted).

since i am using a rigidbody I can easily tell its velocity and such, and I am using a gravity scale of 1.

Arrow must face always the movement direcion.
