For my predictions, I would say I was pretty close for the 14" ramp. The original graphs I made were because i figured with less height, the less far they would go so i made them just a bit too short. With the 21" ramp, I didn't know there was a hill that would cause it to go back down on the graph. The zeros on the graph represent where the time meets the distance. The similarities between the graphs is that the grow positively and all but the 7" graph have a downward slope also. When the graph is rising fast, it shows the effects of the ramps slope and the downward shows the effects of the hill once the skateboard has gone as far as it could. The first two graphs are very similar, the second one just has a lower maximum than the first. The third graph is very different than the others though due to the skateboard not going back into a decline. It just rises. When the graphs are rising the fastest it means that the skateboard's speed is increasing faster and then vice versa for the decreasing. |
