Thermometers measure temperature. Balances measure weight. A stopwatch measures time. A meter is a measure of distance or length.
stopwatch and tape measure
well, a stopwatch and a speedometer will do. Get the speed and time of going through this distance, and multiply by them, you will get the number.
yes you do need to measure with a stopwatch try expierment
In a vehicle it is the speedometer, but this is driven from the transmission. To get an independent measure, use a stopwatch to time a measured mile or other distance.
One person holds the gun and the stopwatch. The other person walks away, unrolling the tape measure ast they go - and stops at an agreed distance. The first person fires the gun - and starts the stopwatch. The second person signals when they hear the shot - and the stopwatch is halted. Divide the time taken for the shot to be heard by the measured distance - and you have the speed of sound.
A chronograph is similar to a stopwatch. Not only does it function as a sort of stopwatch, it can also calculate speed and distance.
-- Mark its location as you start your stopwatch. -- After some time has passed, mark its location again as you stop the stopwatch. -- Measure the distance between the two marks. -- Read the elapsed time on the stopwatch. -- Divide (distance traveled)/(time to travel the distance) . The quotient is the object's average speed during the interval. The shorter the measurement interval, the closer the result is to an instantaneous speed.
