Detailed explanation-1: -Rotation describes the circular motion of an object around its center. There are different ways things can rotate. A very familiar kind of rotation is when a spherical, three-dimensional object turns around an invisible line inside its center. This center is called an axis.
Detailed explanation-2: -"Rotation” refers to an object’s spinning motion about its own axis. “Revolution” refers the object’s orbital motion around another object. For example, Earth rotates on its own axis, producing the 24-hour day. Earth revolves about the Sun, producing the 365-day year.
Detailed explanation-3: -An axis is an invisible line around which an object rotates, or spins. The points where an axis intersects with an object’s surface are the object’s North and South Poles.
Detailed explanation-4: -Rotation. Rotation means to spin on one’s own axis. The Earth for example rotates on its imaginary axis and completes one full rotation every 24 hours.
Detailed explanation-5: -The axis is the imaginary line through the earth that extends from the North Pole to the South Pole. As Earth rotates, it seems like the sun is moving across the sky, but it’s really the Earth that is spinning.
