Today we looked at a video about skateboards and the effect of different ramps on distance traveled. This activity was used to make predictions about graphs and compare them to the actual line. There were three different ramps used, the first distance a 21 inch drop, the second a 14 inch drop, and the final one a 7 inch drop.
My predictions were that the slope for the 21 inch trial would be the most steep. I figured this because the was the most extreme of the three ramps. Things tend to go faster the more they are angled. I didn't expect the graphs to be U-shaped, but my overall predictions were fairly close to realty. I also did not account for the graphs having a roll-back period. Each graph had maximums as well, which I also predicted. Not only did they all hit a maximum, but their maximums were rather close, only differing by a few feet. Both the real and predicted graphs rose and fell at mostly the same rate and place on the coordinate plane too. Overall, my guesses were quite correct. All I really had to do to get accurate readings was watch the video and have a basic understanding of how things like physics work. Sure, my predictions were not perfect but I am pleased with how they turned out.
