The measurement of length and time is calculated the average speed with the expression
[tex]v_{avg} = \frac{\Delta x}{\Delta t}[/tex]
Average velocity is defined as the change in displacement between the interval time
[tex]v_{avg} = \frac{\Delta x}{\Delta t}[/tex]
where [tex]v_{avg}[/tex] is the average velocity, Δx is the displacement in the interval, and Δt the time.
To carry out this measurement, it must be taken into account that the velocity is a vector, for which we define a reference system, it can be a vertical axis with the upward direction as positive, therefore the downward displacement is negative.
A tape measure is placed and the interval during which the scalar distance measurement is performed is defined, the most as is to use time as an independent variable (controlled by the researcher) that is measured with a stopwatch.
The displacement is measured for each given time interval and these two quantities are divided. The sign of the velocity is negative because it goes down
Using the measurements of length and time, the average velocity is calculated with the expression
[tex]v_{avg} = \frac{\Delta x}{\Delta t}[/tex]t
