A ship's speed log measures the speed of the vessel through water by measuring the movement of the ship through the water. It typically consists of a rotor or impeller that rotates with the movement of the water, which is then recorded by a sensor to calculate the ship's speed. This information is crucial for navigational purposes and monitoring the ship's performance.
The speed of ships is typically measured using a device called a speed log, which calculates the speed based on the rotation of a propeller or paddle wheel. Other methods include using radar to track the ship's movement over a known distance or using satellite-based systems like GPS to determine the ship's speed.
An electromagnetic speed log measures the ship's speed through water by utilizing electromagnetic principles. It works by generating a magnetic field around the ship's hull and then measuring the disturbance caused by the water flow as the ship moves. This disturbance is translated into speed readings displayed to the crew.
The knot, equivalent to one nautical mile per hour.
The work done to lift the log can be calculated using the formula: Work = Force x Distance. In this case, the force is 5000 N and the distance is 5 meters. Therefore, the work required to lift the log 5 meters would be 5000 N x 5 m = 25000 Joules.
The work done to lift the petrified log 5 meters can be calculated using the formula: work = force × distance. In this case, the work required would be 25,000 joules (5000 N × 5 meters).

log
That's the ship's log.
The logbook, commonly referred to as "the ship's log." The term originated when ships still measured speed by dropping a log secured with a rope over the side. Evenly spaced knots on the rope were counted over a set period of time, giving us the term "knots" to measure maritime speed. The speed was recorded in in a book which came to be called the "logbook." The ship's log is now used to record anything pertinent to a particular voyage, including speed, weather conditions, engine data, arrival and departure from ports, etc...
How did the jobs on the ships work
Johannes Kepler did not invent log books. Kepler was a German astronomer and mathematician who lived from 1571 to 1630. He is known for his laws of planetary motion and his work on optics. Log books were used for record-keeping on ships long before Kepler's time.
Ships Deck and Engineering logs.
It is a log that merchant seaman use to log their discharges from ships so they are not found to have abandoned a ship illegally.
a ships log -apex
It's referred to as a "Ship's Log."
The detailed and daily records of a ships' progress AND everything else (weather, oil-levels, water-levels, tidyness, tenure, etc) going on onboard the ship is being added almost as it happens onboard into the log book by both Captain and Chief Mate. If the ship has a Chief Engineer, he has a similar book for the engine room.
AIS tracks live ships by Satellite. You can learn more about the AIS and their methods from the official AISlive website. If you are already a member, you can log in to start tracking ships.
