The Physics of Boomerangs Essay -- Science Toys Essays

The Physics of Boomerangs The successful flight of a return looks as though it never should happen. Its more or less circular flight course of action comes from the interaction of two physical phenomena the aerodynamic lift of the arms of the spear thrower and the spinning returns maintenance of angular momentum. Briefly locate, the airfoil at the throwing sticks forward rotating edge provides more lift than its rearward rotating edge. This elevates one side of the boomerang. The spinning object maintains angular momentum by turn of events at a right angle to its axis of rotation. When the spin and the velocity of boomerang are just right, it flies away and returns in an aesthetically fulfil circle.The boomerangs distinctive flight starts with its aerodynamic properties. Boomerangs come in a variety of shapes. The traditional forms are variations on an L with equally large arms. There are also boomerangs with three or even four arms radiating from a center. And there ar e delta boomerangs.1 Whatever the configuration, every boomerang has airfoils at its extremities. Looking outward from the center of rotation of the boomerang, the left side of the blade is the leading edge of the air foil for right-handed throwers.2As the boomerang spins, the airfoils at its perimeter create lift. Our text, Physics A World View, discusses aerodynamics and Bernoullis principle. It explains the relationship between the velocity of a facile and the pressure that the unstable exerts. A fluid gains energy when it speeds up as, for example when it goes through a constricting area in a pipe or passes around an airfoil. Since the gravitative potential energy is constant, the change is in kinetic energy. Since there is an acceleration of the fluid, the press... ...d San Francisco.

Th ey generally have a bit of (undocumented) history/anthropology, some physics, and throwing instructions. For example http//www.gel-boomerang.com/, and http//www.boomerangs.org/ (pictures of some odd shapes).This is consistent with my experience. Trying to limit more spin on the boomerang mainly has the effect of making a throw unnatural and therefore prone to fly into the ground.7When in college, my little girl would often suggest going to throw a boomerang as a first date. Her idea was that she learned a lot about a guy seeing him cope with failing miserably--a certainty the first time out with a boomerang--at a seemingly simple athletic activity.
