Friction and Shoe Slide

Name Brennan Gedney Date November 16, 2011 Graded Assignment Lab shroud Answer the questions, using complete sentences. When you have finished, submit this assignment to your teacher by the due visualise for full credit. (9 points) Score 1. In Part 1, did the force of friction on the raiment seem on the weight of the shoe? If the two are related, why are they? What does the slope of the contrast on the graph of force of friction vs. eight represent? Explain using your data. Answer The frictional force did depend on the weight of the shoe. The more(prenominal) mass a shoe had, the large frictional force was waitd. The more weight a shoe has, the more gravity pulls on the shoe. This means that there is a big normal force, which multiplied by the same coefficient of friction gives a larger frictional force. The slope of the line of friction vs. weight represents the rate at which the frictional force increases due to weight. (8 points) Score 2.Does an athletic shoe wor k better on a basketball court than a dress or leaping shoe? Why or why not? Explain using data from Parts 1 and 2. Answer An athletic shoe does not work better than a dress shoe on a basketball court. Athletic shoes have more grip than dress shoes, and thus require more force to imprint. Based on my data, the dress shoe requires less applied force to move than an athletic shoe. (8 points) Score 3. If you wanted the athletic shoe to mistake faster on a surface, what capability you do to the shoe?Provide at least two ways to make the shoe slide faster, and explain in terms of the force of friction and the coefficient of friction. Answer To make a shoe slide faster, you might decrease the weight of the shoe. This would decrease the normal force, and thus the force of friction, allowing the shoe to slide faster. other way to slide the shoe faster would be to slide it down an inclined plane. This would decrease the coefficient of dormant friction because the angle used in s = t an ? would be smaller. Your Score ___ of 25
