Excellent! In almost every FBD, you will have the Weight of the object. The Weight always acts vertically downwards.

If an object is on a surface, it will experience a Normal Force. Remember normal means perpendicular. So, the direction of the normal force is perpendicular to the inclined plane.

To find the direction of friction, ask yourself in what direction the object would move if not for friction. Friction acts in exactly the opposite direction.
