I am currently in Honors Physics with a pretty poor teacher so I am quite lost after reading all of those different point of views. I read from above that there can be negative work while there can also be negative work? I may need to watch some videos so that my questions can come from a more...

Then I do not understand why the answer to question 6. a) is 'none' on this worksheet: http://www.hartlandhigh school.us/subsites/Andrew-Kartsounes/documents/AP%20Physics%20C/5%20Energy/Masters/Energy%20Packet%202%20Key.pdf

Thank you for the explanation. So would there be work done either negative or positive, or is work = 0?
