What do you mean rotation?
Definition of rotation 1a(1) : the action or process of rotating on or as if on an axis or center. (2) : the act or an instance of rotating something. b : one complete turn : the angular displacement required to return a rotating body or figure to its original orientation.
What is an example of rotation?
Rotation is the process or act of turning or circling around something. An example of rotation is the earth’s orbit around the sun. An example of rotation is a group of people holding hands in a circle and walking in the same direction.
How do you find the rotation?
The point of rotation is the origin, draw lines joining one of the points, say X and it’s image to the origin. You can see that the lines form an angle of 270° , in the counterclockwise direction. Therefore, ΔX’Y’Z’ is obtained by rotating ΔXYZ counterclockwise by 270° about the origin.

What type of movement is rotation?
circular movement
Rotation is a circular movement around a fixed point. Body Movements I: Image demonstrating the various joint movements. There are six types of synovial joints.
What happens in rotation?
A rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point. The fixed point is called the center of rotation . The amount of rotation is called the angle of rotation and it is measured in degrees.
What are the types of rotation?
Rotation Formula
| Type of Rotation | A point on the Image | A point on the Image after Rotation |
|---|---|---|
| Rotation of 90° (Counter Clockwise) | (x, y) | (-y, x) |
| Rotation of 180° (Both Clockwise and Counterclockwise) | (x, y) | (-x, -y) |
| Rotation of 270° (Clockwise) | (x, y) | (-y, x) |
| Rotation of 270° (Counter Clockwise) | (x, y) | (y, -x) |
What is rotation and revolution?
“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.
What is the rotation of the Earth?
Difference Between Rotation and Revolution
| Rotation | Revolution |
|---|---|
| Rotation of the Earth is its turning on its axis. | Revolution is the movement of the Earth around the Sun. |
| The Earth takes 24 hours to complete a rotation with respect to the sun. | The Earth takes a full year (365 days) for one complete revolution around the Sun |
