Copying Google Forms/Sheets Between Users

When working with Google Forms, there are two elements- the sheet (where the responses go) and the form.

It’s not obvious how you might allow another user to copy both a form and a sheet in Google.

So . . . assuming you set the document so that anyone can see it (or share it directly with whomever) . . .

You can append copy to the form URL and it’ll copy the blank spreadsheet and the form.
If you append copy to the sheet URL, it’ll copy the spreadsheet with content and the form.
