At any distance from the axis of rotation, the linear speed of an object is directly proportional to the rotational speed. If the linear speed increases, the rotational speed also increases.

At a given rotational speed how does linear speed change its distance from the axis changes?
In The Center Of The Rotating Platform Right At Its Axis You Have No Linear Speed At All, But You Do Have Rotational Speed. Your Rotational Speed would Stay The Same But As You Move Away From The Center Your Linear Speed Gets Faster And Faster. If You Move Twice As Much From The Center Your Linear (Tangential) Speed Would Also Be Twice as Much
How does rotational speed cange as an object moves away from the axis?
The rotational Speed or angular velocity of an object does not change even if they move away from the axis, however its linear velocity changes.
What is the relationship between linear speed and rotational speed?
(linear speed) = (rotational speed) x (radius or distance from the center) To use consistent measures, use radians/second for rotational speed, meters for the radius, and meters/second for the linear speed. If you know rotational speed in some other unit - for example, rpm (rotations per minute) - convert to radians per second first.

Which has greater rotational speed the shoulders or the fingertips of a figure skater spinning with her arms held straight out?
Rotational speed (degrees per sec) is the same, linear speed is greater at the finger tips.
Which part of earth's surface has the greatest rotational speed about Earth's axis. Which part has the greatest linear speed relative to Earth's axis?
In the case of a solid rotating object, the rotational speed is the same for all parts. The linear speed is greatest at points that are furthest from the axis of rotation - in other words, at the equator.
What is the unit of tangential speed and linear speed?
Tangential speed is how fast a point on a circular object is moving at a certain distance from the center whereas rotational speed is how many degrees (or radians) a point on the circle goes through in a period of time. Every point on a circle has the same rotational speed. The further out you go from the center, the higher the tangential speed is.
What is 1 meter per second in rpm?
Linear speed cannot be converted to rotational speed without knowledge about the distance from the axis of rotation.
What is an example of constant speed with a change in velocity?
rotational motion
What happen to a gymnast's angular momentum when the changes of body configuration during a somersault's.What happen to his rotational speed?
it changes
How are radius and speed related?
Usually they aren't. But you may want to give more details about the specific situation you were thinking about. In the case of rotational movement, the linear speed (in meters/second) is equal to the rotational speed (in radians/second) times the radius (in meters).
What does an ice skater do to change her rotational speed?
She can move her arms inwards - to increase the rotation speed - or outwards - to decrease it.
