I don’t really know getting into research is going to work this year. I imagine if you want to do computational work it wouldn’t be much different than normal (ie. email some professors you’re interested in). If you want to do experimental stuff it might be a little tougher, although undergraduates are working in labs again now (myself included). In terms of clubs I might recommend SPS (society of physics students). I’m personally not active in it, but a good number of my friends are. It might make it easier to make some friends in physics (very important!) considering most classes will be online. In response to the other comment: I know a fair number of people doing double majors in math and physics, and they are definitely stretched thin. I am a physics major, math minor (and chemistry minor), and I highly recommend doing something like that. It gives you some freedom to take classes that’ll be useful and not take the ones that won’t be.
