Question

which has greater angular velocity a hour hand of a watch or of a earth around its own axis?​

Answer 1

Here exactly is what you need to know.

Angular velocity (w)=velocity/radius

Earth radius is about 6400 km and velocity is 30 km/ s

Further for clock it covers distance of 2pi in 3600s so angular velocity (w)=2 pi /3600s

CALCULATE IT AND YOU WILL GET YOUR ANSWER

Answer 2

a watch is 12 hour but a earth has 24 hours due to this the angular velocity of watch is doubled the earth..

so angular velocity of watch is greater..
