Question: how can a bumerang come back to you is it from the wind

Claudia Krehl answered on 12 Mar 2013:

Just like anything that flies boomerangs have essentially two wings in a V-shape. They are flat on one side and curved on the other side, which creates lift when you throw it so it doesn’t fall to the ground immediately. But how do they manage to get back to you? It has actually got nothing to do with the wind, but it is down to the V shaped form.

Because the two sides of a boomerang have different air speeds flowing over them, as it spins the aerodynamic forces acting upon it are uneven. This causes the section of the boomerang moving in the same direction as the direction of forward motion to move faster through the air than the section moving in the opposite direction. These uneven forces make the boomerang start to turn in and follow a circular route, eventually heading back to the thrower.

So essentially because of the V shape boomerangs fly in a circle. But I am sure practice is required too 😉
