Analog Stop Clock
Product Code : SCL-LM-11103
Quick answer: The Analog Stop Clock is a laboratory timer read from a dial, used to measure elapsed time in physics practicals such as timing pendulum oscillations, motion down an inclined plane and cooling experiments. Students start, stop and reset it and read the time directly. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
Many school and college experiments depend on measuring a time interval: the period of a simple pendulum, the time for a trolley to run down an inclined plane, or the time for a liquid to cool through a set temperature range. A stop clock gives that interval directly, and an analog dial lets students see elapsed time as a steady sweep and relate it to the divisions of the scale.
- Reset the clock to zero before the experiment starts.
- Start the clock at a clear reference event, for example as the pendulum bob passes its mean position.
- Stop it after a set number of oscillations or at the end of the run and read the dial.
- Record the reading before resetting, and repeat the timing to take an average.
Timing many oscillations and dividing by their number reduces the effect of human reaction time on the result, a useful point to make when students first use a stop clock.

Frequently asked questions
What is an analog stop clock used for in the laboratory?
For timing experiments: pendulum oscillations, motion on an inclined plane, cooling curves and other practicals where an elapsed time has to be measured and recorded.
How can timing errors with a stop clock be reduced?
Time a number of oscillations, or repeat the run several times and take the average, so that the reaction time in starting and stopping the clock has less effect.
