Friction and Shoe Slide

Name Brennan Gedney Date November 16, 2011 Graded Assignment Lab field of study Answer the questions, using complete sentences. When you have finished, submit this assignment to your instructor by the ascribable date for full credit. (9 points) Score 1. In type 1, did the canal of friction on the horse dress depend on the freight of the fit out? If the two are related, why are they? What does the slope of the hunt on the graph of press of friction vs. eight represent? develop using your info. Answer The frictional force did depend on the tilt of the shoe. The more mass a shoe had, the large frictional force was required. The more weight a shoe has, the more gravity pulls on the shoe. This means that there is a larger 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 a thletic shoe tame better on a basketball game court than a dress or dance 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 indeed require more force to move. Based on my data, the dress shoe requires less applied force to move than an athletic shoe. (8 points) Score 3. If you valued the athletic shoe to slide faster on a surface, what exponent you do to the shoe?Provide at least two slipway 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 king decrease the weight of the shoe. This would decrease the normal force, and thus the force of friction, allowing the shoe to slide faster. Another way to slide the shoe faster would be to slide it down an inclined plane. This would decrease the coefficient of static friction because the move used in s = tan ? would be smaller.
