If I intend to do something that is intentional, if I don’t intend to do something but something happens that is unintentional, it’s like a mistake or a willful act. So for example, if I want to punch someone in the face, it is an intentional act. If I get up and I fall off, and my hand hits him as I’m falling down, I still make contact with his face I still make contact with his face with my hand, but I never intended to do that it was a mistake. It was an accident so I will not be charged with a crime because of that. And the first example, I intended to hit him in the face that is different that is an intentional act so that is the difference between an intentional act and an unintentional act.
