Maxine(linear velocity) = (angular velocity) x radius
All angles must be in radians - and angular velocity in radians / (some time unit), for example, radians/seconds. If you have other units, you must convert. For example, if you have 10 degrees a minute, you can multiply by (pi / 180) to convert to radians/minute. If you have revolutions per second, you can multiply by 2 x pi, to convert to radians per second.
1. You need circular motion for the conversion to work. If the motion is not circular, things are more complicated.

What is the difference between angular and linear diameter?
Angular diameter refers to the apparent size of an object in the sky, measured in degrees, arcminutes, or arcseconds. Linear diameter, on the other hand, is the actual physical size of an object, typically measured in units such as meters or kilometers. Angular diameter depends on the object's distance from the observer, while linear diameter is a fixed measurement.
Is angular speed a vector?
No, angular speed is a scalar quantity. It represents how fast an object is rotating around an axis and is measured in radians per second. It does not have a directional component like a vector quantity.
What are the two kinds of acceleration?
The two kinds of acceleration are linear acceleration, which involves changes in an object's speed along a straight line, and angular acceleration, which involves changes in an object's rotational speed around an axis.
What could Kepler's second law be used to measure?
Kepler's second law says that the line joining a planet to the Sun sweeps out equal areas in equal time. Kepler noticed that when a planet's orbit takes it slightly further from the Sun, it moves more slowly. He deduced from calculations made from observations that when the distance increases by 1%, the angular speed decreases by 1%, so the distance times the angular speed, which is the area swept out per second, stays constant. He found this is true all the time for all the planets, a very important discovery in the history of science. The planet's mass times the distance times the angular speed is the angular momentum, and this stays constant. So angular momentum is 'conserved' as the planet goes round, speeding up and slowing down in its orbit. Therefore the second law is now known as a statement of an important physical principle called the Conservation of Angular Momentum. In this way Kepler's second law contributed to scientific progress after his death. Angular speed is measured in radians per second, and the angular momentum is mass times distance times angular speed. For a single particle it is equal to the linear momentum of the particle (mass times speed), while for a rigid body it is the angular speed times the moment of inertia.
How many Nm do you need to turn a 5kw generator?
power=torque x speed p=txn 5000w= torque x angular speed if the speed of rotation is known, then from above formula we can find the minimum torque required to run the generator.
