Help with arrow physics

I made a bow and arrow game and I got everything down except for the arrow's physics. I want to be able to shoot it and when it starts to lose speed, it kinda tilts down and falls to the ground head first. The way I have it set, when it starts to slow down it kinda just falls down on its side. what do i need to input for it to fall to the ground as if it would in real life. thanks
