Question

A mixer grinder rotates clockwise, its angular velocity will be:

Answer 1

Angular velocity:

1. When a body rotates, the change in the angle along its axis with respect to time is known as angular velocity $\omega =\frac{d\theta }{dt}$
2. We use the right-hand thumb rule to determine the sign of the angular velocity, we curl our fingers in the direction of motion with our right hand if the thumb points in the direction of angular velocity.
3. In the figure, since the direction of rotation is anti-clockwise, the direction of angular velocity is upward.
4. 
5. If the rotation is clockwise, the angular velocity will be downwards.

Thus, the angular velocity will be downwards for the mixer grinder.
