What is tangential velocity and tangential acceleration?
Vt=w*r where; * is multiply Vt is tangential velocity w is omega(angular mometum) r is radius
Quantity that remains constant during uniform circular motion?
-- tangential speed -- angular velocity -- kinetic energy -- magnitude of momentum -- radius of the circle -- centripetal acceleration
Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
Angular acceleration is it scalar or vector?
Angular acceleration is a vector.
What is angular acceleration?
Angular acceleration is the trate of change of angular velocity, often represented by the letter alpha.

A propeller slows from 485 revmin to 188 revmin in 3.00 s. What is its angular acceleration Recall that ac v2r and v rw.?
The angular acceleration is -1.65 revolutions per second^2.
Quantity that remains constant during uniform circular motion?
-- tangential speed -- angular velocity -- kinetic energy -- magnitude of momentum -- radius of the circle -- centripetal acceleration
Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
Angular acceleration is it scalar or vector?
Angular acceleration is a vector.
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 angular acceleration?
Angular acceleration is the trate of change of angular velocity, often represented by the letter alpha.
An electric ceiling fan is rotating about a fixed axis with an initial angular velocity of 0.300 The angular acceleration is 0.898 Its blades form a circle of diameter 0.760?
What do you want to know about it?
Is angular speed the same as angular acceleration?
No. Acceleration and speed are related in the same way irrespective of being linear or angular. Acceleration is rate of change of speed.
What is the magnitude of the acceleration of a speck of clay on the edge of a potter's wheel turning at 45 revolutions per minute if the wheel's diameter is 35?
Firstly I'm assuming that the wheel's diameter is 35cm. If it is not in cm, then you will need to fix the following calculations. a = v2/r Calculating the speed of the clay comes to approximately 1.65m/s Substituting into the formula gives an acceleration of approximately 7.8m/s2 (If you were actually looking for an angular acceleration, you will need to use a different formula)
If you increase the radius of circular motion then what is the centripetal acceleration?
That depends what you will remain constant: the angular velocity, or the speed. Here are two formulae that can help you decide: acceleration = speed squared / radius, and acceleration = angular velocity squared times radius. Angular speed should be measured in radians in this case. Angular speed is equal to 2 x pi x (revolutions per second). From the above formulae, it clearly follows that: (a) If you maintain the speed constant (and thereby reduce angular speed, a larger radius means less centripetal acceleration. (b) If you maintain the angular speed constant (and thereby increase the speed), a larger radius means more centripetal acceleration.
Is there any difference between angular acceleration and radial acceleration?
Yes. A ngular acceleration is to do with something turning. Radial acceleration is linear acceleration perpendicular to the angular acceleration.
