The minute hand should move at a quicker pace of 5.5 degrees per minute, according to common sense (because the hour hand moves 0.5 degrees per minute and the minute hand moves 6 degrees per minute). We begin at 12:01 a.m. The hands are clasped. It takes 1 minute 40 seconds for the clock to sweep from 12:00 to 1:00. Therefore, the minute hand has moved 20 degrees, or 5.5 degrees per minute.
Here's how you can test this yourself: Start with the minute hand at 12:00 and follow it as it sweeps through the next hour. The answer will take 20 minutes to reach 1:00. If your estimate is within 10 percent of the actual value, then you've succeeded in moving your finger at a rate of 5.5 degrees per minute!
The minute hand completes a full round in one hour (that is, 360o). This indicates the hand rotates at a rate of 360o each hour. Both the hour and minute hands are pointing to 12, and we can't tell them apart. The minute hand will eventually eclipse the hour hand. When this happens, it means that the minute hand has moved more than 360o in an hour. We can then say that the hour hand took longer than an hour to complete its rotation.
This experiment shows that the minute hand of a clock sweeps through more than one degree per hour, while the hour hand takes exactly one hour to make a complete rotation. In other words, clocks with minute hands that rotate more quickly than once per hour are accurate while those with minute hands that rotate less frequently than once per hour are not.
As you may have guessed, this experiment requires a clock with a moving minute hand. Modern clocks without this feature would not be able to demonstrate this phenomenon. However, many antique clocks have been preserved which show that this phenomenon was known about 500 years ago!
Minute hands were originally made from wood but now are mostly made from metal because they require very little maintenance and last for many years if treated properly.
Hour hands on the other hand need to be cleaned regularly to ensure clear visibility during reading.
The minute hand rotates 360 degrees in 60 minutes (or 6 degrees every minute), while the hour hand rotates 360 degrees in 12 hours (or 0.5 degrees in 1 minute). Therefore, the minute hand turns at a rate of 6 degrees per minute, or 60 times per hour.
Every hour, the minute hand completes a full circle around the clock. This is the longer hand than the hour hand. The minute hand makes it easy to determine if it's 1:10, 1:15, or even 1:12! So, if the minute hand reaches 1, it's 5 minutes past the top of the hour! If the minute hand doesn't reach 1, it's still at the top of the hour and keeps ticking away!
The second hand moves more slowly because it only turns once per hour. So, if you want to know how many seconds have passed since 10:57, first find out what time it is right now (10:58). Next, count how many times the second hand has turned since then and divide that number by 60 to get the number of seconds passed.
For example, if the second hand has turned once since 10:58 and it's now 11:09, then it's been 9 minutes and 59 seconds since 10:57.
It's important to note that while the second hand only turns once per hour, it can be moving fast or slow depending on what time it is.
The hour hand travels significantly more slowly. When this occurs, it can no longer be seen over top of it. This means that during an eclipse both hands are below the horizon and cannot be seen.
The minute hand is attached to its shaft directly above the second hand. As the minute hand moves, so does the second hand. It's easy to tell which one is which because the minute has 12 marks per circle while the second has 60. So, if you look at your watch and count how many times the minute hand passes through the second hand's position, you can work out how many minutes have passed.
There are 24 minutes per hour, 60 minutes per period and 360 degrees in a circle. Therefore, the minute hand will travel once for every hour it is moving and twice around the clock face in a single day.
During a partial eclipse, only part of the minute hand is visible. During a total eclipse, neither is visible.
Observing the Minute Hand Every hour, the minute hand completes a full circle around the clock. It takes 60 minutes for the minute hand to complete one rotation around the clock face.
The minute hand travels at a rate of 1 mile per hour while the hour hand makes 60 trips in an hour therefore moving 3 miles per hour. A minute hand is smaller than an hour hand and takes less time to make a complete revolution therefore it moves faster.
Minute hands are usually made of metal (usually steel) with sharp tips that mark each minute from 0 to 59. Metal on metal creates a high-pitched noise when shaken. Hour hands are usually made of wood with rims carved to look like minute hands (or plastic, though these are rarely seen in retail stores). Wooden hour hands will darken with use and become softer so they must be re-carved from time to time.
In science classes, minute hands are used as markers for measuring time periods shorter than an hour but longer than a minute - e.g., experiments may need to be conducted for up to a minute after a chemical reaction has been initiated.

The hour hand and minute hand of a clock rotate around its axis at different rates. Because they move at unequal speeds, they form an angle called the "angle of rotation". At any given moment, we can say which direction the angle of rotation is moving by noting which way the hour hand points. If it is pointing to the right, then the angle is closing; if it is pointing left, then the angle is opening up.
What is the angle between the hour hand and the minute hand? The answer depends on how you look at it. If you consider the period when the minute hand makes one complete rotation, then the angle will be zero degrees at exactly twelve o'clock and ninety degrees at exactly three o'clock. Otherwise, if you consider the angle to open up as the minute hand moves from three o'clock to nine o'clock and close as it moves from nine o'clock to three o'clock, then the angle will be 90 degrees at exactly three o'clock and zero degrees at exactly nine o'clock.
