## What is the velocity of clock hands?

You know that the minute hand makes 2pi in one minute (60 seconds). So angular velocity is equal: ω= 2*pi/60 = 1/60 pi. Velocity (perpendicular on the minute hand) is equal to :**v=r x ω=0,055 * 1/60 pi**.

## What is the angular speed of an hour hand in a working clock?

1 Expert Answer

On an analog (not digital) clock, the hour hand travels 360°, or **2π radians**, in 12 hours.

## What is the angular speed of minute hand of a normal clock?

Minute hand of a clock rotates through an angle of 2π in 60 min ie, **3600 s**.

## What is the angular velocity of second’s hand of a watch?

:. **ω=θt=2π60=π30rad/sec**.

## What is angular velocity of minute hand?

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**.

## 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.

## Is the angular velocity of rotation of hour hand?

Hour-hand of a watch completes one rotation in 12 hours, while earth completes one rotation in 24 hours. So angular velocity of hour-hand is double the angular velocity of the earth. This is because **ω = 2 π T** , where T is the time taken to complete one rotation and ω is the angular velocity.

## What are the angular velocity of a second hand minute hand and hour hand of a clock?

The second hand goes through 2π radians in 1 min, or 2π radian/60 seconds, so **ω = π/30 rad.** **s-1 = 0.03 rad.** **s-1**. The minute takes one hour = 60 s/min × 60 min = 3600 s to go around, …

## What is the direction of angular velocity of minute hand of a wall clock?

**Outward from the clock face**.

## What is the average angular acceleration?

The average angular acceleration is **the change in the angular velocity, divided by the change in time**. The angular acceleration is a vector that points in a direction along the rotation axis.
