Question

which is greater ,the angular velocity of a hour hand of a watch or angular velocity of earth about its own axis​

Answer 1

hour hand as it completes 2 rotations in a day and earth completes only 1

Answer 2

The angular velocity of an hour hand watch is 360°/12=30°/hr

=(30°/3600)/s

=(1/120)°/s

In case of earth angular velocity is 360°/24=15°/hr

=(15°/3600)/s

=(1/240)°/s

The angular velocity of earth is less and half that of an hour hand of a watch.
