We took a skate board and rolled it down a ramp at different heights. This showed that the higher the ramp the faster the skate board would move and the farther it would go. We also found that the farther the skateboard went the faster it decelerated. I was pretty close in my predictions. I thought that the 21 inch ramp would have a lower acceleration and maximum height because it was the highest ramp. I was almost right on with the other graphs. The zeros on the graph represented when the skateboard was at the perk of the ramp. All three graphs had different maximums because the all went different distances. The 21 inch ramp went the farthest and the 7 inch ramp went the shortest. Then the slope of each graph was increasing it was accelerating fast so in twas a high slope. When the graph was decreasing it was decelerating at a lower slope.
