What is Angular velocity equal too?
Angular velocity is equal to the change in theta / change in time theta equals the arc length/ radius
A wheel of point 6 m in diameter is rotating at 100 rad per sec The wheel then decelerates uniformly from 100 rad per sec to 50 rad per sec in 50 revolutions Determine the rate of angular acceleration?
Angular acceleration is got by the expression alpha = {(final angular velocity)2 - (initial ang velocity)2} / 2 theta. final is 50 and initial is 100 rad/s. Theta is 50 x 2pi radian Therefore required alpha = -50 x 150/200 pi = -75/2pi radian/s2 Negative sign indicates that the rotation is decelrated.
Why can you let go of the handlebars on a bike and the front wheel stays straight?
Angular Momentum!
Write newton's formula for velocity of sound in air?
If a be the amplitude of a particle executing SHM with an angular velocity w and yis the displacement, then velocity of the particle at any instant is given by u(t)=w J(a 2 y 2
Earth spins on an axis but which part of earth spins the slowest?
The Earth's rotation
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 difference between angular velocity and angular momentum?
angular momentum and angular velocity
Relation between linear velocity and angular velocity?
linear velocity= radius* angular velocity
Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
At time a grinding wheel has an angular velocity of 27.0 It has a constant angular acceleration of 31.0 until a circuit breaker trips at time 2.10 From then on the wheel turns through an ang?
559 g
What is Difference between angular velocity and angular speed?
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
What is the angular velocity in radians per minute of ferris wheel 250 feet in diameter that takes 45 seconds to rotate once?
The angular velocity of a wheel taking 45 seconds to rotate once is 2 2/3 pi radians per minute. The diameter of the wheel does not matter in this case.
Is angular displacement and angular velocity the same?
no, velocity=displacement/time
True or false The angular velocity of a point on a rotating wheel is 40 inches per sec?
False.
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.
Is angular velocity a vector quantity?
Yes, angular velocity is a vector quantity
What is relation between linear velocity and angular velocity?
velosity in circular path angular
