Hello everyone. I am new to the forum. And this is my first question. Consider an experiment with a ball rolling down a ramp. We have to determine several factors effecting its average speed. Please CONTINUE READING BECAUSE THIS IS A DIFFERENT QUESTION THAN THE TRADITIONAL ONES. Now, the factor i was assigned to was "length of the ramp". Now, all factors (slope, angle of elevation, ball type, mass, density, height of ramp and everything else) are all controlled. My prediction was that the speed would increase as the length of the ramp increases. This is because that the acceleration down the ramp is constant. The longer the time, the higher the final speed. When i did the experiment however, i found weird answers. There was no certain pattern! I am really confused. I would like an answer or another explanation of the situation. There could be a mistake as I did the experiment in a hurry and i may have made a mistake. Thanks in advance.
