So for this mini project, we had to watch the video and guess the time-distance ratio and graph it (As seen in Black below). The we got to watch the video in slow-motion, where we could more easily plot the time-distance points (as seen in the lovely pink-pen-under-purple-highlighter).
I'd say I did pretty well as far as guessing the graphs. The 7 inch ramp took me by surprise though, so obviously it looks a little wonky.
The zeros of the graph (where the lines hit the bottom of the graph, on the x-axis) represent the skateboard when it's at the ramp. The lines on the graph make sense because the skateboard is going off the ramp onto an uphill sidewalk, so naturally it'll roll back to the ramp eventually. The 7 inch ramp skateboard actually stopped completely, so it only had one zero, compared to the other two. Obviously all the minimums were the same because #TheRamp.
The maximum for the 21 inch ramp was obviously the highest, because the skateboard had the opportunity to speed up at a faster rate, making it zoom further, faster. Keeping in this theme, the 14 inch ramp has the second highest maximum, and the 7 inch-er was last.
On each of the graphs, the beginning half is when they rise the fastest because that's when the skateboard is launched off the ramp at first. It falls the fastest towards the third quarter of the line because it's still going fast, but its moving back towards the ramp now.
