- Once we had installed all the necessary equipment, we start with the fist data result.
- The compilation of data start with a ramp’s angle form by one book.
- The D.C need to be located at 50cm. Then it is released and you look for the slope in this first try.
- For one book, there might be 6 tries and then a final average for these compilations of results. This would make the results more accuracy.
- Do this process for the other 2 books.
-
Control Variable: Initial position of the D.C in 50 cm. The mass of the D.C
-
Independent Variable: The number of books
-
Dependent Variable: The acceleration for each of the tries.
My hypothesis was right. A D.C depends on a ramp’s angle. The data show how the slopes vary depending on the ramp’s angle. Because when the ramp’s angle was higher, the speed increase and the time decrease. So the slope or acceleration increases when the angle was higher. This shows how the high of the angle elevation affects the acceleration.
Some difficulties during the experiments were that we didn’t have enough space so our classmates move our sensor. As a consequence we have to install the sensor again and again. Another problem was that the computer was freezing therefore we have to start the experiment to many times.
For a better lab, I would take my laptop for make the experiment faster. And it would be easier to make the experiment in an open space or try to organize better the instruments in order that no one can move anything.
