I have major confusion on distinguishing particle verbs and preposition verbs. What defines each? and
are the underlined verbs are particle verbs or preposition verbs?

1. We set up the VCR.
2. That calls for a lot of planning.
3. I'm going to fill out the forms.
4. Let's tear down that shack.
5. Go for it!

Thanks.
