Hi, I try to make a game.When I add rigidbody the object moving z axis. There is mass too.I dont know why .I just want free fall. There is no script on the object.

I found “Edit → Project Settings → Physics/Physics 2D (depending on your project). Change the Y value of the gravity. It’s -9.81f by default (the gravity at Earth). The lowest the value, the more things will fall to the ground.”
