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 else can I help you with?
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 the formula to calculate the average angular speed of an object rotating around a fixed axis?
The formula to calculate the average angular speed of an object rotating around a fixed axis is: Average Angular Speed (Change in Angle) / (Change in Time)
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.
If a body is rotating is it necessarily bejng acted upon by an external torque?
No. Just as no force is required to keep a moving body moving in a straight lineat constant speed, no torque is required to keep a rotating body rotating at aconstant speed. External torque is present only if the body's rate of rotation ischanging.
When the rotational speed of a rotating system doubles its angular momentum?
When the rotational speed of a rotating system doubles, its angular momentum also doubles. This is because angular momentum is directly proportional to both the mass and the rotational speed of the system. Therefore, if the rotational speed doubles, the angular momentum will also double.
If a body is rotating is it necessarily being acted upon by an external torque?
No, a rotating body can maintain its rotation without an external torque if it has an initial angular momentum or is in space with no external forces. However, if the body experiences a change in its rotation speed or direction, then an external torque is likely acting upon it.
A remote control car's wheel accelerates at 22.4 rad-sec squared If the wheel begins with an angular speed of 10.8 rad-sec what is the wheel's angular speed after exactly 3 turns?
A measure of how fast a rotating body is changing its angular position. The average angular speed (w) is obtained by dividing the http://www.answers.com/topic/angular-distance-2 through which the body rotates by the time taken: w = θ/t, where θ = angular distance, and t = time taken in seconds.
Does angular speed depend on distance?
when something moves with constant angular speed (w), as in a rotating disk, the speed (v) as you move away from the center depends on distance (r), but the angular speed does not. Mathematically, v = wr.
Is angular speed the same as angular acceleration?
No, angular speed refers to how fast an object is rotating around an axis at a given moment, usually measured in radians per second. Angular acceleration, on the other hand, describes how quickly the angular speed of an object is changing, or how fast the rotation is accelerating or decelerating.
Do all rotating objects have angular momentum?
Rotating objects all have angular momentum.
What is the approximate angular speed of a wheel rotating at the rate of 5.0 rev per second?
The exact angular speed is 5*360 = 1800 degrees per second. The appoximate speed could be 2000 dps
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.
