## What happens when a rotation occurs?

A rotation is a transformation in a plane that **turns every point of a figure 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.

## How do you describe rotation transformation?

**Rotation turns a shape around a fixed point called the centre of rotation**. Rotation is an example of a transformation. A transformation is a way of changing the size or position of a shape.

## What is rotation short answer?

“Rotation” refers **to an object’s spinning motion about its own axis**. … For example, Earth rotates on its own axis, producing the 24-hour day. Earth revolves about the Sun, producing the 365-day year.

## What do you need to describe a rotation?

A rotation is a turn of a shape. A rotation is described by **the centre of rotation, the angle of rotation, and the direction of the turn**.

## What are the three things needed to describe a rotation?

**Three pieces of information are needed to rotate a shape:**

- the centre of rotation.
- the angle of rotation.
- the direction of rotation.

## How would you describe an enlargement transformation?

Enlargement is an example of a transformation. A transformation is a **way of changing the size or position of a shape**. To enlarge a shape, a centre of enlargement is required. When a shape is enlarged from a centre of enlargement, the distances from the centre to each point are multiplied by the scale factor.

## How do you describe transformations?

A translation moves a shape up, down or from side to side but it does not change its appearance in any other way. Translation is an example of a transformation. A transformation is **a way of changing the size or position of a shape**. Every point in the shape is translated the same distance in the same direction.

## How do you explain transformations in math?

A transformation is **a way of changing the size or position of a shape**. Every point in the image is the same distance from the mirror line as the original shape. The line joining a point on the original shape to the same point on the image is perpendicular to the mirror line.

## What causes rotational motion?

**When a torque (rotational analogue of force) is applied to a body (system of particles) about an axis**, it provides a twist and this causes rotational motion. This is simply analogous to the case of translational motion where force is the cause.

## What are the elements of rotational motion?

**Inertia, Damper**, Spring – Elements of rotational motion.

## What is rotation and its effect?

The spinning of the Earth on its axis from west to east is called rotation. Effects of the Earth’s rotation are: **The rotation of the Earth causes the day and the night**. … Because of the speed of rotation, a centrifugal force is created which leads to the flattening of the Earth at poles and bulging at the center.
