What is the best example for conservation of angular momentum?
In case of Russian dance, the dancer will spin her body about the vertical axis passing through her toe. If she keeps extending her hands then number of rotation and so angular velocity will be less. If she brings her hands close to her body then number of rotations would increase. Same scene could be enjoyed in case of circus with girls hanging just with a tight hold with their teeth.
How do you find the angular velocity of second hand of a watch?
Angular velocity has units of (angle per time), usually stated in radians per second. (1 whole revolution = 2 pi radians) Assuming the watch is operating properly, the second hand turns once per minute. 1 rev/minute = (2 pi) / (60 seconds) = pi/30radians per second. This is usually good enough for most physicists, but if they demand a number, it's easy to work it out: pi = 3.14159 (rounded) Angular velocity = pi/30 = 0.10472 radians per second. Or if you really want the physicist to take notice, tell him "104.72 milliradians per second".
Why angular speed is called angular frequency?
Because angular speed is some number of revolutions or angle rotated each second. It has units of s-1 (per second) and is therefore a frequency.
What is the numerical ratio of velocity to speed an object?
The size of velocity and the size of speed are the same number. But velocity also has a direction and speed doesn't.
What is the difference between speed and velocity speed?
Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
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.
Why do planets rotate around the sun in the same direction?
They don't rotate in the same direction. But most of the rotation comes about from the conservation of angular momentum. Angular momentum is given by L=m*w*r2 where m is the mass, w is the angular velocity in radians per second, and r is the radius of the circular motion. Due to conservation of angular momentum, if the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). Hope I answered your question...

Angular velocity of the water wheel?
number of angles moved in 10 seconds divided by 10.
What is the larger of the two mating gears?
The gear with the greater number of teeth; it will have a lower angular velocity .

How do you find angular velocity in radians per second?
-- Determine the number of revolutions, vibrations, reciprocations, or full oscillations in one second. -- Multiply that number by (2 pi).
How do you calculate number of rotation in Circular motion?
f=1/T where f is the frequency and T is the time for one rotation... Example.. If the time for one rotation = 2s then frequency =0.5Hz (1/2) therefore... the number of rotation in one minute = 60x0.5=30 in 1 second = 1x0.5=0.5

The angular momentum quantum number 1 indicates the?
The angular momentum quantum number, symbolized by l, indicates the shape of an orbital.
Revolutions per minute to linear velocity?
After any whole number of revolutions, the total displacement is zeroand so the average velocity is zero.At any instant, the magnitude (speed component) of instantaneous velocity is(pi) x (distance from center of rotation) x (RPM / 30) units per second.
Velocity in avogadro's number?
Avogadro's number does not have anything to do with velocity.
Formula for velocity of a wave?
v=lambda*f v is velocity, lambda is wavelengt, f is frequency Units are m/s, meters, Hertz Or v=w/k v is velocity, w(supposed to be greek letter omega) is angular frequency, and k is the wave number Or If you want to get complicated the velocity of a wave can be seen in the wave equation. This requires partial derivatives, look into it for calculus based physics
