A "Full Rotation" refers to a complete turn around a central point or axis, typically measuring 360 degrees. This concept is commonly used in various fields, including physics, engineering, and even in everyday activities like spinning or turning. For example, when a top spins, it completes a full rotation when it returns to its original position. In the context of Earth, a full rotation takes approximately 24 hours, which defines the length of a day. This rotation is responsible for the cycle of day and night, as different parts of the planet are exposed to the Sun at different times.
