During Science class we are in the unit motion. We have done an experiment with motion detectors. In that experiment we had to move things so we could match a graph. We did that by moving back or front, at different speeds. Here are the graphs, the blue lines are the beginning graphs and the red are the ones that we did.

For this graph we first moved back, then at the straight line we kept the same speed and then we came closer again to get the line down.

Also on this picture, you cannot see the whole graph but I will also explain the last part that you cannot see. I think we first went closer and then we went back and at the end we stood still because the end of the graph was in the middle.

For this one we went closer and then stopped for about a half second, then went closer and stopped again but for one second. After that I went back again.

For this last graph it was metres per seconds and for this graph we used a trash can to do the graph. But this graph was particularly difficult. First I did not move, then I moved back to make the line go up. Then I did not move so It would get in the middle. Then I went fast closer so the graph would go down, but you cannot see that on the image.
