Today we used a Newton meter to drag a shoe along the table. The pulling force is equal to the friction force, so we were able to measure the friction force with the Newton meter. To keep the test fair we used the same surface (a table) for each shoe. We took each measurement three times, and wrote the three measurements in order. We used the middle measurement (the median) each time. Finally we looked at our results and drew conclusions. Whose shoe had more friction?
