On an analog (not digital) clock, the hour hand travels 360°, or 2π radians, in 12 hours.
What is the speed of the hour hand on a clock?
Answer: the answer is π/21600 rad /s.
What is the angular speed of second’s hand of a clock?
Its angular velocity is π30 radians per second (about 0.105 radians/s.
What is the angular speed of the hour hand of a 12 hour clock?
On an analog (not digital) clock, the hour hand travels 360°, or 2π radians, in 12 hours.
What is the angular velocity of hour hand and minute hand?
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 in rad s 1 of the hour minute and second hand of clock?
What is the angular velocity in rad s^(-1) of the hour minute and second hand of a clock ? π21600rads-1;π1800rads-1;π30rads-1 . ∴ω=2πT=2π60×60=π30rds-1 .
Is the angular speed of rotation of hour 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 value of angular speed for 1 revolution?
This result is the basis for defining the units used to measure rotation angles, Δθ to be radians (rad), defined so that 2π rad = 1 revolution.
What is the angular velocity of the minute hand?
It completes a full rotation around that circular clock in 60 minutes. So the angular speed of the minute hand is 2 * pi / 60 = pi / 30 = (approximately) 0.10472 radians/minute.
How do you calculate angular velocity?
We can rewrite this expression to obtain the equation of angular velocity: ω = r × v / |r|² , where all of these variables are vectors, and |r| denotes the absolute value of the radius. Actually, the angular velocity is a pseudovector, the direction of which is perpendicular to the plane of the rotational movement.
What is the 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.
