Experiment Evaluation This Experiment probably has different answers as everybody else because my group made the ball roll in a slippery surface, unlike the rest of the class who used the rug. Our answer may be a lot longer but they are just as accurate, because our ball slid for much longer in the plastic mat placed on the hallway between the Middle School and High School building. All the numbers were taken to be as accurate as they can possibly be. The only mistake that could have entered the experiment is that the floor in which we rolled the ball might not be a flat, there may have been small bumps that the human eye cant see but do affect the force on the ball while it is rolling.
