  We need to obtain the same tables than in the other experiment but we are going to use a different method. We place the cardboard at a stable point so that the friction is measured at the same angle. We compile the data from the different experiments into 16 tables and insert a graph for each table. We use these averages to complete the table, and finally, we create a graph showing how the experiment turned out.

The inclined plane movement. You will calculate the coefficient of friction between to surfaces using the mobile phone as your instrument to take measurements. When we have the measures we put a graphic for each table of experiments and put the data when the mobile starts to move in a table with all the data. Later we calculate the averages and the error.

  Here is the original photo: Here is the final result of the lilas image: First I choose a nice image. Then, in gimp I open the photo and duplicated the layer and change one of this layer to black and white. When I have this, with the scissors select tool I select the parts I want to stay in color. Later, I click in the middle of the part selected and I go to select, invert and delate. Finally I save the photo as png.
