The metre stick accelerates towards the ground at a known rate, thus by knowing the distance it traveled it is possible to compute the time it took to travel that distance.
A laser measuring device can calculate distance. However, measuring distance with a laser measure can be easier or more difficult depending on the model you purchase.

For measuring distance, meter is used. For measuring mass, kilogram is used. For estimating time, second is used.
It depends on what you want to measure. A unit that is suitable for the distance between subatomic particles will be of little use in measuring intergalactic distances (and conversely).
to measure distance
with a measuring tape.

With a long measuring tape.
we can measure the distance by meter scale

You can measure your reaction time by dropping a ruler between your fingers.
