Kimberly Cuthbert-Holmes March 16, 2008 St. Thomas Aquinas Mrs. Guzas Science - Lab Report I. Introduction In this lab, Shannon and I were investigating the affect of different materials on the force of friction. Our question was how do different sliding surfaces affect the friction of objects. The physical property of different surfaces affects the amount of friction that results when they encounter each other. The greater the friction force between the two surfaces, the greater the force needed to cause motion. With this being said, I think the smoother the surface, the less friction the surfaces will have when they are in contact, causing the object to move quicker. This experiment can be applied to a real-life situation. The friction between the tires of your automobile and the road determines your speed. Depending on the weather conditions or the material the road is made of, can affect your speed. When it is raining, your car tends...
