A direct object would become a subject if you put it in the passive voice: In "I am going to pick up the ball with all of my hand", "I" is the subject, "the ball" is the direct object while "with all of my hand" is an indirect object. Only the direct object can become the subject in passive voice: "The ball is picked up with all of my hand (by me)" -> Here, the former subject "I" becomes an object "me". The former direct object "the ball" is now the subject.
