The Physics of Tossing a Pizza

Tossing pizza dough is very important to get the proper thickness and consistency of dough to make a pizza with. It also helps with the development of better standing wave ultrasonic motors, but more on that later. Professional pizza tossers know and scientists have proven that the best way to toss a pizza from rest is in a spiral. This is because a large amount of torque is required to get the dough spinning and all the rotation it has will be created when it leaves the throwers hand. However, after the dough is spinning when the tosser wants to toss it again they should use a semi-elliptical motion so the dough flies through the air at an angle based on the condition it is in when it hits their hands. This is more risky because it is easier to toss the pizza incorrectly since each additional toss puts it further from a helical path which is why beginning pizza tossers only do one toss at a time.
Pizza tossing is similar to ultrasonic motors since they both convert torque applied over a short time to continuous rotational motion. Scientist can measure details about the pizza's flight, such as the number of rotations, initial torque and angle of rotation to design better motors.
Here are some really cool pizza tossing tricks.
