Observing the graph carefully, it seems as if the person kept a constant speed on the first trial, but on the second trial it seemed as if the person accelerated at the 75-100 meter distance. Mylisa pretty much stayed the same. My data could have had some slight errors because I do not know if the recorders who were doing the timing could have made a mistake. I have learned that acceleration is all the same as speed and velocity, but has some slight differences. Acceleration is the rate change in velocity.
Velocity is the direction and rate of change in position.
Speed is just the rate of change in position. In this lab we used all of these principles.
