Earth is not the only object that rotates. Amusement park rides, such as Ferris

wheels or carousels, also rotate. The Ferris wheel rotates around a horizontal axis, and

the carousel rotates around a vertical one. Wheels on a car rotate around a strong

horizontal bar called an axle. Many household items rotate including sprinkler heads, beaters on a mixer, blades on a ceiling fan, and doorknobs.
