Question

why is the center of gravity of boomerang outside its body​

Answer 1

Explanation:

The center of gravity can be located within or outside the body depending on the bodys configuration and position; it is inside an object when the object is uniform and outside the object when it is not uniform. ... It is the point of exact center, around which the body may rotate freely in all directions

Answer 2

Answer:

If the body contorts, the center of gravity may move OUTSIDE the body. Bending the body in different ways moves the center of mass in different directions. This is often used by acrobats and trapeze artists. They make moves that look incredible by moving the CM out of their bodies.
