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.


How do you find out the direction of angular accelaration?

The direction of angular acceleration comes from whether the angular speed of the object is clockwise or counterclockwise and whether it is speeding up or slowing down.The direction of the angular acceleration will be positive if the angular velocity is counterclockwise and the object's rotation is speeding up or if the angular velocity is clockwise and the object's rotation is slowing downThe direction of the angular acceleration will be negative if the angular velocity is clockwise and the object's rotation is speeding up or if the angular velocity is counterclockwise and the object's rotation is slowing downThe angular acceleration will not have a direction if the object's angular velocity is constant


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.


What is the difference between angular velocity and angular momentum?

angular momentum and angular velocity

When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?

Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.

What is the difference betweentangential velocity or angular velocity?

angular velocity s the rotational analague of linear velocity...direction of linear velocity s along tangent to the circle while that of angulr velocity s along the axis of rotation.the direction of angular v can be find by right hand rule which state that if the axis of rotation s held n right hand with fingers curled round the direction of rotation then the thumb will mark the direction of angular velocity.... the magnitude of angular velocity that s the angular speed is represented by the length of the line along the axis of rotation...its units are rad/sec,degrees/sec or revolution/sec while that of linear velocity s m/sec...


What is an angular speed of a rotating body?

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).


How can you find the direction of angular momentum if the position vector and force vector lie on the plane?

By finding the direction of angular velocity because it's always parallel to it.


What direction does the angular velocity vector of the Earth's rotation point toward?

The Earth's angular velocity vector due to its axial rotation points towards the north pole.

Can uniform angular velocity has acceleration?

No, uniform angular velocity means no angular acceleration.
