Rotation Definition
Rotation can be defined as the circular motion of an object around its centre or some axis. There can be an infinite number of imaginary lines or axes around which an object rotates. When an object undergoes rotation, all the particles comprising the object move at the same velocity around that axis. In general, rotation is one of the 4 types of transformations. Rotational motion is complex as compared to linear motion.
Rotation may be clockwise or anti-clockwise and an object can be rotated at different angles in rotation. When the rotation is in the clockwise direction, the angle of rotation is considered negative whereas it is considered to be positive in the case of anti-clockwise rotation.
The below image shows an object when rotated through different angles in clockwise and anticlockwise directions.
Let us have a look at the rotation formula.
Rotation
In real life, we know that the Earth rotates on its own axis and the moon also rotates on its axis. But what basically rotation is? Also, geometry deals with four basic types of transformations that are Rotation, Reflection, Translation, and Resizing. In this article, we shall read about the fundamental concept of rotation.
