In Physics we had a lab about Time vs. Position. (Which we found out equals speed) Using a battery-run car we were to see where the position of the car was after a certain amount of time. When it came time to discuss, we all had similar looking graphs and data. The only differences included the units the position was measured in and the difference in the time intervals. Having this "difference" in the data, didn't stop us from concluding that with speed and position it is always constant. In class, a questioned popped up as if the one of the points should be at (0,0) on the graph. Honestly, I was a little confused on that but I believe there would be a point (0,0) only if there was no error during the lab. I believe the y-intercept shows how much error occurred in the lab, and many sources of error can be found in this lab. We also discussed if velocity, had a role in this lab. We know that Speed is distance/time and Velocity is displacement/time. I believe we do use a constant velocity because we are not "changing the direction" but we are allowing it to go in the same direction. Overall, I come to know that the lab shows that no matter what, if you have a constant speed you will have a constant position no matter what.
