ELI5 how do frisbees work?
gpt
2 forces are at work
1) gyroscopic stabilisation -- the fast spinning keeps the frisbee flat and steady. If the frisbees 'lip' was any thinner, there wouldn't be enough material to maintain a spin.
2) aerodynamic lift -- the frisbee has about the same curvature as the top of an airplane wing, so the movement through the air causes lift. If the frisbee was flat on top, it wouldn't fly as well.
