The linear (tangential) speed of a point on a spinning circle is
(angular speed of the spin) x (radius of the circle). Note that this only works if the angular speed is in units of radians/time .
To convert degrees to radians, multiply by (pi)/180 ... about 0.01745 .
To convert angular speed (Ī) to linear speed (v), you can use the formula v = rĪ, where r is the radius of the rotating object. This formula shows that the linear speed is equal to the product of the radius and the angular speed.
Angular velocity = angle / time
(or)
Angular velocity = 2 x pi x radius of circular path / Period
(or)
linear velocity= cross product of radius and angular velocity
(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.
average speed is total distance covered in total time. For example, if a body covers a distance d in time t and a distance D in time T, then its average speed will be
v=(d+D)/(t+T)
v=w*r
v-linear speed
w-angular(rotatinal) speed
r-objects radius
Angular momentum is the product of the moment of inertia, and the angular velocity.
Angular speed =
(size of the angle turned in some period of time) divided by (the time taken to turn that angle).

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.
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.
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 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.
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 (Ī) = linear speed (v) / radius (r). This will give you the angular speed in radians per second.
How do you convert angular speed to linear speed?
divide the linear speed by the radius
How to convert Angular velocity to velocity?
To convert angular velocity to linear velocity, you can use the formula: linear velocity = angular velocity * radius. This formula accounts for the fact that linear velocity is the distance traveled per unit time (similar to speed), while angular velocity is the rate of change of angular position. By multiplying angular velocity by the radius of the rotating object, you can calculate the linear velocity at the point of interest on that object.
Question about linear speed and angular speed?
what is the relation angular speed and angular speed with clutch disc plate
When a particle is moving on a circular track of radius r with angular speed W the linear speed of the particle will be?
The linear speed of the particle moving on a circular track can be found using the formula v = r * Ī, where v is the linear speed, r is the radius of the circle, and Ī is the angular speed of the particle.
Relation between linear speed and angular velocity?
Linear speed is directly proportional to the radius of rotation and the angular velocity. The equation that relates linear speed (v), angular velocity (Ī), and radius (r) is v = rĪ. This means that the linear speed increases as either the angular velocity or the radius of rotation increases.
What does the linear speed of a rotating object depend on?
The linear speed of a rotating object depends on its angular speed (how fast it rotates) and the distance from the axis of rotation (the radius). Linear speed is calculated as the product of the angular speed and the radius.
What is angular speed and angular velocity?
That is analogous to linear speed and velocity, but for rotation. Whereas a linear speed (or velocity) is expressed in meters per second (or some other units of distance / time), the angular speed or velocity is expressed in radians / second (or some other units of angle / time). Of course, when something rotates, there is also a linear speed, but different parts of an object rotate at different linear speeds, whereas the angular speed is the same for all parts of a rotating object - at least, in the case of a solid object. For example: the Earth rotates at an angular speed of 1 full rotation / day. The linear speed at the equator is approximately 1667 km/hour; close to the poles, the linear speed is much less.
How do you find angular speed without radius?
Angular speed is calculated by dividing the linear speed by the radius. If the radius is unknown, you would not be able to directly find the angular speed without more information about the motion.
How is the centrifugal speed calculated?
The centrifugal speed can be calculated using the formula v = rĪ, where v is the speed, r is the radius, and Ī is the angular velocity. This formula relates the linear speed of an object moving in a circle to its distance from the center and how fast it's spinning.
Why does angular speeds stay the same even though the linear speeds are different?
Angular speed is defined as the rate of change of angular displacement, while linear speed is the rate of change of linear displacement. If the object is rotating without changing its angular speed, then the linear speed will vary with the radius of rotation. This relationship allows angular speed to remain constant while linear speeds differ.
When either a linear or angular speed is changing with time the difference in speed per unit time is called the?
The rate at which speed changes with respect to time is called acceleration. It can refer to changes in linear speed (velocity) or angular speed. Positive acceleration indicates an increase in speed, while negative acceleration (deceleration) indicates a decrease in speed.
