Science 7 Science motion graphs September 28, 2015 Salonee Leave a comment This was a hard graph to do. we learned that going backward makes the bar go up and going closer to the sensor make it go down. the bars was very sensitive. we were very close to being accurate. I just stood there and it made a straight line I stepped forward and i stood there and the scale went up I stood there but then i moved back and then it started to go random because the scale was too sensitive.
