We did these steps for three trials. At the end of the lab we found out that the runner ran faster each time. We also found out that the farther away the distance, the longer it takes you to get there. The shorter the distance, the faster the time. However, there was human error, so the time may not have been precise.
Human error is a common thing that happens to every human being.
Of course, that's why it's called human error. This occured because each time taker could have press the stop watch when the runners foot crossed the line. Others may have stopped the watch when the runner's whole body was over the line. By doing so everyone's time may have been a little off. In order to calculate the velocity and acceleration of the runners lab, we used various equations.
