Rotational effects refer to the impact of an object's rotation on its physical properties and behavior. For example, when a spinning object, like a top, rotates, it experiences forces that can affect its stability and motion. This is due to the distribution of mass and the speed of rotation, which can lead to phenomena such as gyroscopic stability. In larger systems, such as the Earth, rotational effects influence various natural processes. The Coriolis effect is one such phenomenon, where the rotation of the Earth causes moving air and water to turn in predictable patterns, affecting weather systems and ocean currents.
