I'm doing a school project on how math and physics are used in video games, and I'm trying to find things that I could talk about. The main idea I have right now is how trig is used to calculate the changes in x and y values of an object based on its speed and direction to get full circular movement, but I can't really think of much else worth talking about that I really understand. I thought of gravity/friction, but that's a bit simple (just adding or subtracting a value to the x or y values of a velocity). I suppose I could also talk about collision detection, but that's also a bit simple (at least simple 2D collision detection to the degree that I understand it).
So I was jsut wondering if anyone had any ideas for things I could talk about. Try and keep them from being too complex if possible.
Thanks to anyone that helps! :)
