Hey guys, I'm in high school and we have to do a presentation on any physics topic we like. The teacher is just trying to assess our class as it is only the beginning of the school year. It has to be a minimum of 3 min and maximum of 5 min. Are there any topics that aren't too complicated, but still abstract concepts to fit into 5 minutes? Anything but quantum mechanics and special relativity because I'm sure a lot of my friends are going to do them, and I want to stand out (gotta give a good first impression, am I right?) Thanks again.
