A boomerang works because the wings are

made so that they are flat in the back and curve

towards the front, which gives it an increase in

air pressure under the wing, giving it lift.

The curved parts of the boomerang face the same direction, allowing it to move in a circular path.

The boomerang also works like a gyroscope!

The boomerang moves vertically and also

spins in the direction given by the right

hand rule. Because the top is moving faster,

it spins as well as moves, creating a twisting

effect, like a gyroscope.

Equations

F=centripetal force N

m= mass kg

V=velocity m/s

R=radius m

L=Lift force N

P=density of boomerang kg/m (g/cm)

v=velocity m/s

CL= lift coefficient

A=area of airfoil (The area of the boomerang) m^2
