Answer :
Hour hand of a watch or a clock turns 1 complete circle in 12 hours. Its angular velocity = 2 π / 12 hours = π/6 radians / hour
Angular velocity of revolution of earth around its own axis = 2π / 24 hours
= π/12 radians / hour
So the angular velocity of the Hours hand in a watch is more than that of the Earth about its own axis.
Angular velocity of revolution of earth around its own axis = 2π / 24 hours
= π/12 radians / hour
So the angular velocity of the Hours hand in a watch is more than that of the Earth about its own axis.
Answer:
The angular velocity of hour hand is equal to the twice of angular velocity of earth
