Technically manga and cartoons as well as anima and animated cartoons (Is there an english word for them? In german they are called "Zeichentrickfilm") are the same. The only difference regarding the naming is the country they were made in.

Of course in practice we see quite a gap in style and quality (most times) and intended age groups (most cartoons are made for children or juvies), though there are exceptions like Sin City and 300 - both of which are comicbooks later adapted into movies (and both contain plenty of mutilated corpses).

A really massive difference though are the voice actors. In english the vast majority of animated cartoons is voiced by people who sound like they just do a job (and often enough a poor one to boot), while the japanese voice actors really live their role.
