- A frisbee is essentially a circular airplane wing. The convex shape of the top surface leads to a high pressure on the bottom, and a low pressure on the top of the disc, providing lift.
- The reason a frisbee doesn't reach 35,000 feet like an airplane is an airplane has engines which give it constant propulsion. A disc gets all of its kinetic energy from the throw, and essentially glides back to earth following the throw.
- According to a study done by the University of California, for a frisbee thrown at 30 m/s and a drag coefficient of 0.033, the maximum theoretical disttance is 186 meters, while real world tests gave an average of 70-170 meters.
