Types and Sensitivity of Stopwatches

Stopwatch thermometer emitter and what meter there are two types of stopwatches. Two types of stopwatches this is called the Analogue start stopwatches and the lab stopwatches watch the sensitivity is 0.2 seconds, you need to know the sensitivity. I will discuss the sensitivity with you later this is a nod a stopwatch it's also analog but the sensitivity is 0.1 now. How do we know which one is 0.1 which means 0.2, okay now this one around 60 seconds okay one around 60 seconds so the sensitivity is 0.2.

There is another types of analog stopwatch one around only 30 seconds that year went around the DNA after a continued 31 32 33 34. Okay for this analog start watcher the sensitivity is 0.1 so both of these are interlocked start watching this is digital stopwatch. it's a digital stopwatch and the sensitivity is 0.01 1 seconds 0.1 second 0.01 seconds sensitivity 0.01, so there are two types of stopwatches analog can digital and for analog also two types one with 0.2 seconds sensitivity another one is with 0.1 second sensitivity the sensitivity now for this stopwatch one round 60 second right run around 60 seconds

 If we have a closer look at this patter closer look at this part so they will see something like this so this is 0 1 2 3 4 5 seconds ok 0 1 2 3 4 5 seconds then we can see that from 0 to 1 seconds. There are 5 divisions right 5 unit here so 1 seconds divided by 5 unit so therefore the sensitivity is 0.2 seconds the second type this one so this is 0 seconds 1 seconds 2 seconds now from 0 to 1 0 to 1 there are 10 divisions right from 0 to 1 10 divisions so therefore each one is 0.1 seconds so the sensitivity is 0.1 seconds.

This is the stopwatch with 30 second one round this is 60 second one round these are 30 second when round so you must be careful about the sensitivity of stopwatch especially the digital stop oscillator especially the analog stopwatch because it has two different you have two types with different scale important note the accuracy of time measurement can be increased by repeated measurements and taking the average value okay because sometimes made you to random error and to reduce random error we take a few reading and then find them the aberration and the accuracy depends on the users reaction time for example that if you want to measure the times when you see let's say is in the Atlantic's games okay this person runs you want to measure how much time he ran there so you are standing here you're standing here holding a stopwatch and then you measure the times.

when you see him running you see him running 1 2 3 run you take let's say 0.1 second to response 0.1 seconds means that you see him run after 0.1 second day only you start pressing x' on this this stopwatch so we say your reaction timer your reaction time is 0.1 seconds you see after 0.1 second then only you press this is the rest reaction time so this is an error right okay suppose you should use to start earlier but because you react slower so then this cost error and when you stop here also maybe let's say you take another 0.1 seconds to response and then you will make the reaction times that becomes 0.2 seconds and 0 point 1 second at the beginning since 0.1 second data back at the end of the rear the this running okay so the accuracy depends on the action timer if you can react very fast and the arrow is very low if you reacts slowly and then the reaction time will be very high this may be asked in objective questions so you must know the accuracy depends can be reduced by taking average and the accuracy depends on the users reaction time you English (auto-generated)
