How does a change in radius effect linear velocity?
For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.
What is the relationship between rotational speed and linear 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.
Would it be correct to say that the Doppler effect is the apparent change in the speed of a wave due to the motion of the source?
No. The Doppler effect is about a change of frequency, not about a change of speed. The relative speed may change as well, but that's not what the Doppler effect is about.
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
Does the wave speed change in the Doppler effect?
Yes, the Doppler effect defines the change in speed of a sound wave due to motion. As I recall, the Doppler Effect is a change in the frequency of a wave, not its speed. Yep, I'm pretty sure Doppler is a frequency change, not a speed of sound change.

For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.
How do you convert angular speed to linear speed?
divide the linear speed by the radius
How do you convert linear speed to angular speed?
To convert linear speed to angular speed, divide the linear speed by the radius of the rotating object. The formula for this relationship is: angular speed (ω) = linear speed (v) / radius (r). This will give you the angular speed in radians per second.
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.

How does linear speed change as rotational speed changes?
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.
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).
How is a change in motion described?
In linear or axial motion, a change in speed, a deceleration or an acceleration.
How do you calculate linear speed?
Linear speed = change in linear displacement (from some fixed point)/time for that change. [Although this works in all everyday situations, the Theory of Relativity shows that there is no fixed frame of reference and so no fixed point.]
Would it be correct to say that the Doppler effect is the apparent change in the speed of a wave due to the motion of the source?
No. The Doppler effect is about a change of frequency, not about a change of speed. The relative speed may change as well, but that's not what the Doppler effect is about.

What is the polygonal effect in chain drives?
Module and chain links moving around the radius of the sprocket causes the linear belt speed to vary. The pivot rod travels on the pitch diameter of the sprocket while the module moves through the smaller chordal radius causing a horizontal rise and fall of the module. This polygon effect is typical to all Modular Belt systems. The magnitude of speed variation is dependent on the number of sprocket teeth.
