Rotational speed is inversely proportional to the radius. A smaller radius will result in higher rotational speed, while a larger radius will result in lower rotational speed. This relationship is described by the equation v = rω, where v is linear speed, r is radius, and ω is angular velocity.

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.
How is tangential speed affected by the radius?
Tangential speed is directly proportional to the radius. As the radius of an object increases, its tangential speed also increases. This relationship is described by the equation v = rω, where v is tangential speed, r is the radius, and ω is the angular velocity.
What happens to tangential speed as rotational speed increases?
we can say that tangential speed of the object is linearly proportional to the distance from the center. Increase in the distance results in the increase in the amount of speed. As we move to the center speed decreases, and at the center speed becomes zero.
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 speed of a point on the rim of an object in motion?
The speed of a point on the rim of an object in motion is determined by the object's rotational speed and the distance of the point from the center of rotation. This speed is calculated using the formula: speed radius x angular velocity.
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.
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 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.
What are the units for rotational speed?
the units for rotational speed are radians / sec or degrees / sec
A space habitat is designed so that the variation in g between a person's head and feet is less than 0.01 g If the person is 2 m tall then the minimum radius of the habitat is?
This cannot be answered at once. One has first to set the maximum rotational speed. The (pseudo-)gravity equals the rotational speed (in radians per second) squared times the radius (in meters).
What happens to the number of revolutions of a rubber stopper as the radius of rotation decreases?
As the radius of rotation decreases, the number of revolutions of a rubber stopper increases. This is due to the conservation of angular momentum - with a smaller radius, the rotational speed must increase to maintain the same angular momentum.
Does the electromagnetic attraction of an electron to the nucleus of an atom strengthen when rotating faster like gravity?
Neither the electromagnetic or gravitational forces are affected by rotational speed.
