Winnowing is an agricultural method rooted in physics, used to separate grains from lighter impurities like dust or chaff. In this process, a person throws a mixture of grains and chaff into the air, allowing the wind to blow away the lighter particles while the heavier grains fall back down due to gravity. This technique relies on differences in mass and density, with gravity pulling the heavier grains down more quickly while the wind carries away lighter particles. Winnowing is a cost-effectiv
