Section 1: How does a boomerang work?
This is a simplified explanation, but it hits the important points:
1. A boomerang has “arms” shaped like airplane wings—they create lift.
2. The boomerang is moving forward and the boomerang is spinning– creating an uneven lift.
3. The uneven lift created by the spinning boomerang makes it turn (like leaning on a bicycle)—and keep turning until it makes a circle and comes back to you.
Let’s start with number 1: the boomerang arms are shaped like wings. Notice the cross-section of the boomerang. The wing has a flat side and a curved side. Notice also that it has a rounded, more blunt edge and a tapered, sharper edge, like an airplane wing. The blunt edge is called the leading edge and the tapered one is called the trailing edge.
