Q:

# How does a Frisbee fly?

A:

A Frisbee flies because its design creates a low-pressure area on top of the object and a high-pressure area on the bottom, giving the Frisbee lift. The thrust is given by the arm of the person throwing it, while the spin imparts stability.

Frisbees fly because of the shape of the object and the kinetic energy imparted as it is thrown. The rim of the Frisbee allows air to move over the top of the object faster than the air moving below it. The faster moving air on top of the Frisbee has a lower pressure than the slower moving air across the bottom, causing the Frisbee to fly. The spin of the Frisbee as it flies gives the object stability through angular momentum, keeping it level and maintaining a smooth and steady flow of air around the Frisbee. The stability imparted by the spin also ensures that the Frisbee sustains the proper angle of attack, which is the ideal angle at which the Frisbee much fly to ensure the most lift.

The principle of the Frisbee's design is easily tested by turning it upside-down and then throwing it as normal. The Frisbee can still fly when thrown inverted, somewhat, but is much more unstable and the amount of lift generated is significantly less.

Frisbee launchers are devices used when playing with dogs that allow owners to launch discs farther than they are typically able to be thrown. This provides more exercise for the dogs, which must run farther and faster to catch the Frisbees.

In the physical sense, breadth is defined as the measure of the second-largest dimension of an object or its width, whereas depth is generally the distance from the top to bottom or from the front to back of an object. Breadth and depth are also used to explain how a person understands the world. People can have breadth or depth knowledge about particular subjects, notes the University of Guelph.
