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.
