Procedure 1. Collect three of your school textbooks that are different size and weight (you can use books: of various sizes that you have at home as well). - y . _ 2. Record the weight of each of the books before experimenting. 3. Find three different surfaces to slide floor. etc). 4. Being sure not to damage the textbook, slide the textbook along various surfaces, keeping a keen eye on the frictional force that each surface has on the movement of the textbooks. . 5. Record the time and distance that each book traveled on the three different surfaces on your provided Frictional Force worksheet. . 6. Tie strands of string around each textbook, and this time, pull each book and record the time it takes to pull the same distance you pushed the book on the three surfaces.

Some forces are in direct contact with objects, while other forces are not. For example, the force of friction slows the football down when it rubs against another object. Friction is a force that resists motion between two bodies in contact. You can observe friction when you roll a football on the ground. The ball will eventually come to a complete stop after rolling, because the friction caused by the football dragging on the ground depletes the force that was initially enacted upon it. For this assignment will be conducting an experiment with motion, frictional force, and learn how such frictional forces may affect the game of football.
