Knots are used to measure speed on ships or boats. The term comes from the way people measured the speed the boat was traveling. They did it by tying knots on a rope at regular intervals and would then throw the rope overboard, counting the number of knots that were pulled overboard in a certain amount of time.

What is a equation use to calculate speed?
There are several equations that involve speed; the basic equation, that defines speed, is: speed = distance / time Which is often written as: distance = speed x time This assumes constant speed. For variable speed, the limit should be taken, resulting in: dv = ds/dt where v is the velocity, s is the position, and t is the time.
How much is 1 knot?
One knot is equivalent to 1 nautical mile per hour. A nautical mile is slightly larger than a standard mile, as it is 2000 yards, so 1 knot is slightly faster than 1 mph.
Why is it easier to tie a knot with cotton strings as compared to silk strings?
The whole goal with a knot is to create as much friction between each of the strings as possible. The greater the friction, the better the knot will hold. Silk string is very smooth as compared to the cotton string. So the friction produced when a cotton string is tied in a knot is greater than that when a knot tied with silk string. That is why a knot tied with cotton string will hold better than a knot tied with silk string.
What is the relation between instantaneous speed and instantaneous velocity?
If I drive away from my house at 8:00 in the morning and return at 6:00 PM that same evening with 50 more miles showing on the car, you know immediately that my average speed for the day was 5 mph. But you don't know a thing about how much of that time I was stopped, how much in motion, or what my speed was at any moment between 8 and 6, because there's no necessary relationship between instantaneous and average speed. I guess it's probably true to say that there has to be some instant during any period of time when the instantaneous speed must be equal to the average speed during the same period. That sounds like a nice theorem, and its proof ought to be good for some mathematical recreation, but it doesn't seem too useful.
Speed of sound in coffee?
1497 metres per second is the speed of sound in water at 25 degrees C. The speed in coffee will vary slightly with the density but will not be much different.
How much is 22knots in kilometers?
The 'knot' is a speed of 1.852 kilometers per hour.
How do you know how much time something took if you know its speed and distance?
time=distance x speed. to find speed, it is speed=distance/time distance=speed x time.
Which information can be used to help find the speed of the ball?
Distance traveled divided by how much time determines speed. Speed=distance/time
Differences between WANs and LANs in terms of speed control access media cost and distance?
Well distance is pretty obvious. LAN's are usually in a uni campus, school or home. A WAN is over a much larger distance, i.e., a series of office buildings spread over a large area.
How much time is required for a bicycle to travel a distance of 100 meters at an average speed of 2 meters per second?
Time = Distance/Speed = 100/2 = 50 seconds.Time = Distance/Speed = 100/2 = 50 seconds.Time = Distance/Speed = 100/2 = 50 seconds.Time = Distance/Speed = 100/2 = 50 seconds.
How can you calculate average speed from a distance -time graph?
Speed is distance divided by time so pick the section you want to work out the average for, work out how much distance has been traveled in that section and divide it by how much time has passed for that section.
How do you find speed ratio?
The speed ratio is typically calculated by dividing the speed of the input gear by the speed of the output gear in a gear system. This helps determine how much the output gear rotates in relation to the input gear in a given amount of time.
How much is Knot in kilometres per hour?
1 knot = 1.852 km/h
Does a car traveling the logest time always travels the gratest distance?
Not necessarily. The distance a car travels is determined by its speed and the time it spends traveling. If a car is traveling at a slower speed but for a longer period of time, it may not cover as much distance as a car traveling at a faster speed but for a shorter period of time. So, the longest time does not always correspond to the greatest distance traveled.
What are the information about speed and velocity?
some may feel speed and velocity are same terms but both are diffrent,let seehow? Speed=distance travelled/time,that means it depents on how much distance you travelled,its a scalar quantity that means it dont depents on the direction velocity:it depents on diaplacement,ie;velocity=displacement/time,displacement is the measure of smallest distance between mean position and last,its a vecter quatity,so its value can be negetive,+ve,and may zero
At a given rotational speed how does linear speed change its distance from the axis changes?
In The Center Of The Rotating Platform Right At Its Axis You Have No Linear Speed At All, But You Do Have Rotational Speed. Your Rotational Speed would Stay The Same But As You Move Away From The Center Your Linear Speed Gets Faster And Faster. If You Move Twice As Much From The Center Your Linear (Tangential) Speed Would Also Be Twice as Much
How much time does it take to drive 145 miles?
Just divide the distance by the speed.
