hello everybody

in class i did an experiment and i lunched a metal cart down a ramp and recorded the data from the ticker timer and than i plotted a position- time graph.

http://img466.imageshack.us/my.php?image=positionvstimemt0.jpg

one of the questions asks what type of motion was the cart undergoing? and how can you tell by the shape of the graph?

what would you guys/girls the answer is for the above questions?(i included a photo of the graph above)

thanks alot!:)

Not sure what is meant by the phrase, "type of motion," unless they are talking about accelerated motions vs. non-acceleration motion.

If that's the case, the graph definitely shows accelerated motion. You can tell that because the distance traveled each second increases as time goes by. For example, the distance traveled in the 3rd second (between t=2 and t=3) is clearly greater than the distance traveled in the first second (between t=0 an t=1). That means the avg. speed in the 3rd second is greater than the avg. speed in the first second. If the speed is changing, the motion is accelerated motion.

If there were no acceleration, the cart would travel the same distance during each second. The graph in that case would be a straight line. Whenever the graph is something different from a straight line, you can conclude that acceleration occurred.
