Why does a boomerang return to its thrower?
A boomerang is a flat, curved, usually wooden object configured so that when it is thrown, it returns to the thrower. Two well-known scientific principles explain the characteristic flight of a boomerang: (1) the force of lift on a curved surface caused by air flowing over it (lift is the force that causes an object to lift or rise); and (2) the unwillingness of a spinning gyroscope to move from its position. (A gyroscope is an instrument consisting of a wheel that spins around a rod through its center. The wheel continues spinning in the same direction, even when the direction of the instrument is changed.)
When a person throws a boomerang properly, he or she causes it to spin end-to-end, vertically. As a result, the boomerang will generate lift, but it will be to one side rather than upward. As the boomerang spins vertically and moves forward, air flows faster...
