What is the angular speed of a windmill with 40 feet and speed of 80 revolutions per minute?
The angular speed is 480 degrees per second.
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
What is the angular momentum of the 2.6 kg 5.6 cm diameter rotating disk.?
Without knowing the angular speed, i.e. RPM or some such velocity, it is not possible to answer the question. Please restate the question, giving all of the required information.
True or false a point hat is 1 in from the center of a rotating wheel on a car has the same angular velocity as a point that is 2 in from the center?
True.
Solution and answer of angular velocity?
It is the rate of change - with respect to time - of the angular displacement.
Do all rotating objects have angular momentum?
Rotating objects all have angular momentum.
What moment of inertia does not depend on angular velocity?
An object that is rotating at constant angular velocity will remain rotating unless it is acted upon by an external torque.
What is an angular velocity?
An angular velocity is the angle turned in a given time by a body rotating around an axis.
A rotating fan blade has kinetic energy when rotating with constant angular velocity when the angular velocity is reduced to one third what will happen to the kinetic energy?
It will decrease by a factor 9.
What is the angular speed of a windmill with 40 feet and speed of 80 revolutions per minute?
The angular speed is 480 degrees per second.
Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
Yes, suppose a body is rotating anti-clockwise, then its angular velocity and angular momentum, at any moment are along axis of rotation in upward direction. And when body is rotating clockwise, its angular velocity and angular momentum are along axis of rotation in downward direction. This is regardless of the fact whether angular velocity of the body is increasing or decreasing.
Why is angular momentum used?
In the same way that objects in linear motion tend to remain that way, objects which are rotating tend to keep rotating. Thus, we need both linear and angular (rotational) motion.
What has angular momentum?
Anything that's spinning, rotating, tumbling, or traveling in a closed path around something else, has angular momentum.
When the rotational speed of a rotating system doubles its angular momentum?
Gets doubled
As a rotating cloud collapses its rate of rotation?
The law of conversation of angular momentum.
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.
How do you increase the angular velocity of a rotating object?
Angular velocity just means how fast it's rotating. If youaa want more angular velocity, just rotate it faster or decrease the radius (move it closer to the center of rotation). Just like force = rate of change of momentum, you have torque= rate of change of angular moment Or We can increase the angular velocity of a rotating particle by applying a tangential force(i.e. accelaration) on the particle. Since the velocity of the particle is tangential with the circle along which it is moving, the tangential accelaration will not change the diriction of the velocity(as angle is 0),but will cause a change in magnitude. Thus angular velocity will increase.
