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.
Which move faster the minute hand or the hour hand?
After the hands meet, the angle between them starts to increase because the minute hand moves faster than the hour hand. The hands will meet again when the angle between them reaches 360o. In an hour, the minute hand covers 330o more than the hour hand.
Which hand moves the slowest on a clock?
The hour hand moves slowest of all, taking twelve hours (half a day) to make a complete rotation.
How much faster is the minute hand of a clock?
The minute hand is twelve times faster than a hour hand.
What is the type of speed of the hands of the clock?
There are four types of speed and they are: Uniform speed. Variable speed. Average speed.
What is the second hand on a clock?
the thing that points to the hour on a clock or watch. The thing that points to the minute is called the minute hand, and the thing that points to the seconds is called the second hand.
When was the minute hand added to clocks?

What is the fourth hand on a clock?
The fourth hand is a 24 hour hand that is used to tell the hour in another time zone. The fourth hand can be set independent of the hour hand to measure another time zone and with the rotating bezel a third time zone can be measured.
Is minute or second hand longer?
The seconds hand extends perfectly out to the minute/second markers, and is the longest hand of the three, which does make the whole ensemble seem more proportional.
Why is hour hand shorter?
Originally Answered: Why is the hour hand shorter than the minute hand on a clock? Its because it’s easier to decipher the time at a quick glance. At 6 o’clock the hands are directly opposite eachother but at half past 12 the smaller hand is half way between 12 and 1.
How long does it take for the hour hand to travel once around the clock?
They should realize that the hour hand moves through an interval between minute markers every 12 minutes.
What is speed class 11?
Speed. Speed of an object is defined as the ratio of path length and the corresponding time taken by the object. i.e., Speed = Distance travelled/Time taken. Speed is a scalar quantity.
What speed is Class 9?
Average speed is defined as the total distance travelled by the body in total time i.e.
What is speed class 9th?
Speed: Distance travelled by the object in unit time. The SI unit of speed is metre per second. This is represented by the symbol m s–1 or m/s. Speed is a scalar quantity; it only has direction.
