I know this sounds like an impressively easy answer but here's the problem.
I am in a pickle due to grammar and I can't for the life of me find my answer anywhere online.
I have had a friend make the claim that saying:
I worked on experimenting new things within a company.
is the same (just different semantics) as saying
Experiments were performed on me within a company.
I know there's a proper term for this where one is an active voice, doing something and the other is a passive voice, having something done to you but I don't know what specifically it is called so I can't look up the proper terminology or lesson to teach why the two scenarios are extremely different and depressingly enough it's putting a strain on a friendship of mine.
I just want to know what is grammatically correct and I need it explained in simple terms to someone who is not an English major.
