Today I did some research into golf discs because I'm wanting a couple to practice with. There's actually a lot of engineering that goes into them. The different ratings on certain brands indicate the results of that applied physics. Anyways, in my research I watched this video about speed ratings. There are a couple physics lessons in it I really enjoyed.
I think the reason these lessons stick with me so well is that the physics is immediately applied to the real world. And, I suppose, as well as being directly related to a game I enjoy haha
