The direction of the angular velocity vector is along

What is the direction of the angular velocity of the minute hand of a clock ?

Assertion: If the head of a right handed screw rotates with the body, the screw advances in the direction of the angular velocty. Reason: For rotation about a fixed axis, the angular velocity vector lies along the axis of rotation.

The wheels of an airplane are set into rotation just before landing so that the wheels do not slip on the ground. If the airplane is travelling in the east direction, what should be the direction of angular velocity vector of the wheels?

Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity. Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.

Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity. Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.

A body is executing circular motion in the vertical plane containing directions. If the direction of velocity (oversetrightarrow(v)) at the top most point is towards west, what is the direction of angular velocity (oversetrightarrow(omega))?

(A): The direction of velocity vector remains unchanged though the coordinate system is changed (R) : The direction of real vector is independent of coordinate system

A particle is moving with constant speed v along x - axis in positive direction. Find the angular velocity of the particle about the point (0, b), when position of the particle is (a, 0).

The linear velocity of rotating body is given by vecv = vecomega xx vecr where vecomega is the angular velocity and vecr is the radius vector. The angular velocity of body vecomega = hati - 2hatj + 2hatk and this radius vector vecr = 4hatj - 3hatk , then |vecv| is

The dimensional formula for angular velocity is
