Stopwatch Wikipedia. Stopwatch animation for 5. A stopwatch is a handheld timepiece designed to measure the amount of time elapsed from a particular time when it is activated to the time when the piece is deactivated. A large digital version of a stopwatch designed for viewing at a distance, as in a sports stadium, is called a stopclock. In manual timing, the clock is started and stopped by a person pressing a button. In fully automatic time, both starting and stopping are triggered automatically, by sensors. A typical mechanical analog stopwatch. The timing functions are traditionally controlled by two buttons on the case. Pressing the top button starts the timer running, and pressing the button a second time stops it, leaving the elapsed time displayed. A press of the second button then resets the stopwatch to zero. The second button is also used to record split times or lap times. Download Gossip Girl Season 1 All Episodes. When the split time button is pressed while the watch is running, the display freezes, allowing the elapsed time to that point to be read, but the watch mechanism continues running to record total elapsed time.

Mechanical stopwatches are powered by a mainspring, which must be periodically wound up by turning the knurled knob at the top of the watch. Digital electronic stopwatches are available which, due to their crystal oscillator timing element, are much more accurate than mechanical timepieces. Because they contain a microchip, they often include date and time of day functions as well. Some may have a connector for external sensors, allowing the stopwatch to be triggered by external events, thus measuring elapsed time far more accurately than is possible by pressing the buttons with ones finger. Stopwatches that count by 11. The first digital timer used in organized sports was the Digitimer, developed by Cox Electronic Systems, Inc. Salt Lake City Utah 1. Watch Chicken Run Online Free 2016. It utilized a Nixie tube readout and provided a resolution of 11. Its first use was in ski racing, but was later used by the World University Games in Moscow, Russia, the U. S. NCAA, and in the Olympic trials. The device is used when time periods must be measured precisely and with a minimum of complications. Laboratory experiments and sporting events like sprints are good examples. The stopwatch function is also present as an additional function of many digital wristwatches, cell phones, portable music players, and computers. Popular cultureeditThe popular newsmagazine 6.

A stopwatch is a handheld timepiece designed to measure the amount of time elapsed from a particular time when it is activated to the time when the piece is deactivated. Human error on using stopwatcheditEven though stopwatch is created to be more accurate, human still make an error in every time they use stopwatch. Normally, human will take about 1. Therefore, most of the calculation error are happened because of this reason. To get more accurate result, most of the researchers use propagation of uncertainty equation in order to reduce error on every experiment2. Error propagation from Harvard Universitys bookQ is the sum of uncertainty between a 2 and b2. For example The result from measuring the width of a window is 1. In most of the science experiment, researchers will normally use SI or International System of Unit on any of their experiment. For unit of time that we observe on the stopwatch, generally we will use minute and second3. See alsoeditExternal linksedit.
