rotation

When something turns like a wheel, over and over again, it's in rotation. You can't feel the earth's rotation even though you know it's happening.

Even if you find the rotation of clothes in the dryer comforting, it's best to remain on the outside looking in. Rotation can also mean a series that repeats. A baseball team has a "pitching rotation" (five pitchers who take turns starting games), while a song that's on the radio every fifteen minutes is on "heavy rotation."
