Compare the angular velocity of the earth around its own axis with that of the hour hand of a clock?
Earth's rotation = 1 rev / day. Hour hand = 1 rev / 12 hours = 2 revs / day. The angular velocity of the hour hand is double that of the earth. Numbers: Earth = 2 pi / 24 hours = 2 pi / 86,400 = 7.27 x 10-5 sec-1 Hour hand = 2 pi / 12 hours = 2 pi / 43,200 = 1.45 x 10-4 sec-1
What else can I help you with?
What is the angular velocity of the hour hand of a clock?
Angular velocity = angle covered / time taken Hence angular velocity of the hour hand = 2pi/ 12*3600 = 1.4 x 10-4 rad/s
What are the magnitude of the angular velocity and the angular accelaration of the second hand of a clock?
-- The angular velocity isone revolution/minute = 360 degrees/minute = 6 degrees/second .(2 pi) radians/minute = pi/30 radians per second . -- If the clock is working properly ... not starting, stopping, speeding up, orslowing down ... then the angular acceleration of any of its hands is zero.
Why cant a clock travel at constant velocity?
A clock cannot travel at a constant velocity because the movement of the clock's components would affect its timekeeping accuracy due to factors like gravitational time dilation and relativistic effects. Maintaining a constant velocity for all parts of a clock while in motion would require overcoming these effects, which is currently not feasible.
How do you find the acceleration of a second hand?
The second hand of a clock completes one full rotation in 60 seconds. Given that acceleration is the change in velocity over time, the second hand experiences a constant angular acceleration of 0.1 rad/s^2 as it moves in a circular path.
With respect to a stationary clock a moving clock will register that time ticks?
slower due to time dilation as predicted by the theory of special relativity. This is because the moving clock is experiencing time differently as a result of its velocity relative to the stationary clock.
What is the angular velocity in radians per second of the second hand of a clock?
The angular velocity of the second hand of a clock is pi/30 radians per second.
What is the angular velocity of the hour hand of a clock?
Angular velocity = angle covered / time taken Hence angular velocity of the hour hand = 2pi/ 12*3600 = 1.4 x 10-4 rad/s

Which of the clock arm rotates are constat speed or constant velocity?
Ignoring the fact that some clocks "jump", for example once a second, each of the three arms moves at constant angular velocity. The speed, in this case, is constant; the velocity is not since the direction changes. On the other hand, sometimes people use a vector to describe an angular velocity. Angular momentums add nicely with vector representation.
Which has more angler velocity hours clock rotation of earth around its axis?
hours clock is more anguler
What will be the path of moving clock if its velocity is comparable to velocity of light?
If the velocity of the moving clock is comparable to the speed of light, it will experience time dilation, length contraction, and relativistic effects according to the theory of special relativity. The path of the clock will be distorted from the perspective of a stationary observer, and its time measurements will differ significantly from those made by a stationary clock.
What is the speed of a clock's second hand?
A clock's second hand makes one complete revolution each minute. Thus, by definition, it is rotating at one revolution per minute or one RPM. That's its "rotational velocity" and it is the same no matter how big or small the clock might be. The actual velocity that the tip of the second hand might trace out as it revolves around the center of the clock will vary with the length of the second hand. The longer the hand, the faster the tip moves around the circumference.
Why cant a clock travel at constant velocity?
A clock cannot travel at a constant velocity because the movement of the clock's components would affect its timekeeping accuracy due to factors like gravitational time dilation and relativistic effects. Maintaining a constant velocity for all parts of a clock while in motion would require overcoming these effects, which is currently not feasible.
What is the angular acceleration of the minute hand of a clock?
The hands of a clock move at a constant speed, not slowing or speeding up. Therefore, the acceleration is a constant 0 rad/s2
How do you find the acceleration of a second hand?
The second hand of a clock completes one full rotation in 60 seconds. Given that acceleration is the change in velocity over time, the second hand experiences a constant angular acceleration of 0.1 rad/s^2 as it moves in a circular path.
When was Twist Around the Clock created?
Twist Around the Clock was created in 1961.
With respect to a stationary clock a moving clock will register that time ticks?
slower due to time dilation as predicted by the theory of special relativity. This is because the moving clock is experiencing time differently as a result of its velocity relative to the stationary clock.
