-- The angular velocity is
one revolution/minute = 360 degrees/minute = 6 degrees/second .
(2 pi) radians/minute = pi/30 radians per second . -- If the clock is working properly ... not starting, stopping, speeding up, or
slowing down ... then the angular acceleration of any of its hands is zero.

How is angular velocity related to tangential velocity?
The time, T , it takes for an object to go thru one comblete rotation of 360 degrees or 2pi radians is its "period." The rate at which it completes the rotation is its "angular velocity." The rate is the angle (in radians) divided by the time. So , Angular Velocity = 2 pi / T.
How is the radius of rotation related to the centripetal force and angular velocity?
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
What is the physical significance of angular velocity?
Angular velocity means how fast something is turning around. Often measured in radians per second, or revolutions per minute.
Define angular speed?
In physics, angular frequency ω (also referred to by the terms angular speed, radial frequency, circular frequency, orbital frequency, radian frequency, and pulsatance) is a scalar measure of rotation rate. Angular frequency (or angular speed) is the magnitude of the vector quantity angular velocity. The term angular frequency vector is sometimes used as a synonym for the vector quantity angular velocity.[1]One revolution is equal to 2π radians, hence[1][2]whereω is the angular frequency or angular speed (measured in radians per second), T is the period (measured in seconds), f is the ordinary frequency (measured in hertz) (sometimes symbolised with ν),
Explain the term angular velocity?
Angular velocity is a measure of how fast something is spinning. It can be measured as either degrees per second or radians per second. 1 turn per second would be 2 PI radians per second or 6.283185... rad/sec or 360o /sec
What is an angular speed of a rotating body?
Angular velocity is given as radians per second; angular speed is also the same thing. Velocity is a vector with magnitude and direction and speed a scalar with magnitude only. The magnitude is identical; velocity will define the direction of rotation ( clockwise or counterclockwise).
What is the angular velocity in radians per second of the second hand of a clock?
The angular velocity of the second hand of a clock is pi/30 radians per second.
How do you convert radians per second to meters per second?
the tangential velocity is equal to the angular velocity multiplied by the radius the tangential velocity is equal to the angular velocity multiplied by the radius
What is the formula for the angular velocity?
There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.
What is the angular velocity of the wheel before braking began if the wheel rotates through 6 radians in 2 seconds as it is uniformly brought to rest?
It was 6 radians per second. Angular acceleration = -3 radians per second2 Initial angular velocity = 6 radians per second. Final angular velocity = zero. Average angular velocity = 3 radians per second. Angular displacement in 2 seconds = 3 x 2 = 6 radians.
What is the angular velocity in radians per second of a pulley turning at 1800 RPM?
The angular velocity of a pulley turning 1800 rpm is 60 pi radians per second.
How is angular velocity related to tangential velocity?

How the angular velocity of binary stars are calculated?
By observation. The angular velocity can be derived from the period. If, for example, it takes a day (86,400 seconds) for a full revolution, then the angular velocity will be (2 x pi / 86400) radians per second.
What is angular momentum?
Angular momentum is an expression of an objects mass and rotational speed. Momentem is the velocity of an object times its mass, or how fast something is moving times how much it weighs. Therefore angular momentum is the objects mass times the angular velocity where angular velocity is how fast something is rotating expressed in terms like revolutions per minute or radians per second or degrees per second.
Define constant angular velocity and explain how it is applies to a CD?
Angular velocity is the measure of angular displacement (in one or the opposite) direction over a unit period of time. In the context of CDs , one unit in which this can be measured is the number of revolutions per second. A constant angular velocity means that the CD is turning through the same angle each second.
What does angular mean?
Angular momentum is an expression of an objects mass and rotational speed. Momentem is the velocity of an object times its mass, or how fast something is moving times how much it weighs. Therefore angular momentum is the objects mass times the angular velocity where angular velocity is how fast something is rotating expressed in terms like revolutions per minute or radians per second or degrees per second.
