Measuring Speed in the Laboratory

The video tutorial explains how to measure speed in a laboratory setting using the equation speed equals distance over time. It covers three experiments: using a stopwatch to measure the speed of a marble on a slope, using a light gate to measure the speed of a trolley, and measuring the speed of an oil drop on a tile. The tutorial emphasizes the importance of accuracy and minimizing human error in time measurements.
