rotate
Definition
Rotate means to turn around on an axis. An axis is an imaginary line that goes through the centre of an object and around which the object turns.
When something rotates, it moves in a circle. The direction of rotation can be clockwise or counterclockwise.
We can see rotation all around us. The Earth rotates on its axis, and this is what causes day and night. The planets in our solar system also rotate on their axes.
Rotation is important for many reasons. It helps to keep objects in shape. It also helps to create gravity, which is the force that pulls objects towards each other.
How can the word be used?
The Earth rotates on its axis once every 24 hours.
