Rotations, often referred to as spins, describe the movement of an object around a central point or axis. In physics, this concept is crucial for understanding how objects behave in motion. For example, the Earth performs a rotation on its axis, which takes approximately 24 hours to complete, resulting in the cycle of day and night. In mathematics, rotations can be represented using angles, typically measured in degrees or radians. A rotation can be clockwise or counterclockwise, and it can be applied to shapes in geometry, such as triangles or circles. Understanding rotations helps in various fields, including engineering, animation, and robotics.
