Is the angular speed of the hour hand of a clock greater than less than or equal to the angular speed of the minute hand?
The hour hand of a watch takes 12h to complate one rotation i.e. T1=12 hour. And the earth takes 24 hours to rotate once around its axis, i.e. T2=24 hour. i.e., angular speed of hour hand is greater than the angular speed of earth around its axis.
What is the angular velocity of second hand minute hand and hour hand of a clock?
Since the minute hand of a clock completes a circular revolution in 60 minutes, the angular velocity of the minute hand is, ω=2π60×60=π1800=1.75×10-3rad⋅s-1 . Since the hour of a clock completes a circular revolution in 12 hours, the angular velocity of the hour hand is, ω=2π12×60×60=π21600=1.45×10-4rad⋅s-1.

What is the angular velocity of hour hand of watch?
Answer. Answer: the answer is π/21600 rad /s.
What is the angular speed of minute hand of watch?
Minute hand of a clock rotates through an angle of 2π in 60 min ie, 3600 s.
How often does the tip of an hour hand on a clock have the same velocity?
Answer: tip of an hour hand on a clock have the same velocity? once every minute; once every hour; once every 12 hours; once every 24 hours.
What is the average angular speed of the second hand on a clock?
There are 2π radians in one complete rotation, and that takes the second hand 60 seconds to complete. 2π /60 = pi/30 radians per second# which is about 0.105 radians per second.
What is the angular acceleration of a clock’s second hand?
The second hand of a clock goes. through an angular displacement of 2π in one minute. Its angular speed is w = 2p/60s = 0.105/s. The direction of w is perpendicular to the face of the clock, pointing into the face of the clock. The average angular acceleration of the second hand is zero.
What is angular velocity of minute hand in wall clock?
Hence, the angular velocity of the minute hand on a clock is π1800rad/s.
What is angular displacement of minute hand in 20 minutes?
It is simple: In 60 minutes, the minute hands makes a full revolution of 360 degrees. So in 20 minutes it revolves one third, or 120 degrees.
What is second hand in physics?
The hand that moves around the fastest on an Analog Clock. It shows the number of seconds. There are 60 seconds in a full rotation of one minute.
