So i need to find out the form of a particular song, and i dont know how to do this. actually, i dont really know what form is. could someone please help me!!!

also, if anyone could help me out with the meanings of the following words that would be great:
-motivic and thematic development

I'm pretty sure the meter is the same as the time signature, and I THINK cadence has something to do with the particular chord that the song is based upon. Other than those, I have never even heard those terms used in music.
