What is the difference between an argument and persuasion? (english 1)

An argument is a clashing of views and is typically heated and angry. To persuade someone is more to use logic, ethos, pathos, etc to get someone to agree with you. To persuade someone is to reason with them and is generally more calm.

In an argumentative essay you have to pick a side on a subject that has two sides, and with evidence you must prove why your argument is valid. It should be objective, but it also should include a paragraph stating the opposition, and why you don't agree with it. Persuasive is more of your opinion, and yes also should be backed up with facts, but in this case your trying to persuade the reader to take your side. It's a much more personal essay.
