A physicist from Netherlands named Felix Hess examined how a Boomerang works. According to the physicist, a Boomerang works with 2 principals.
First, a Boomerang works by using the Bernoulli’s Law; that for the same height at the same fluid. As a result, the faster the fluid rate, the smaller the pressure. The second principal is taken from the Newton’s 3rd Law of Motion. This …
