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...
angular momentum and angular velocity
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
linear velocity= radius* angular velocity
No, uniform angular velocity means no angular acceleration.
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel
no, velocity=displacement/time
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.
Yes, angular velocity is a vector quantity
Orbital Velocity is calculated in m/s where as angular velocity is calculated in rad/s.. Answer is very clear.. angular velocity is calculated when body is rotating around a axis and a reference point is needed to calculate it.. where as orbital velocity is calculated when body is moving around a bado in circular path, nt around itself... e.g. Earth rotates around so it have angular velocity .. it also rotates around sun in orbit so it has Orbital velocity also :)
velosity in circular path angular
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
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.
