Unformatted text preview: LAB REPORT FOR M1 EXPERIMENT: FRICTION VI-1: Parts VI-1 and VI-2 deal with the friction of a pan as it is slid across a level metal surface. The goals of these parts are to establish a value for the coefficient of kinetic friction ( k μ ) for 2 different substances; Teflon and rubber. To obtain this constant I must first establish a relationship between k μ and my gathered data. This relationship is t k b m m μ = . Where b m is the magnitude of the force required to move the pan, and t m is the total mass of the pan plus the masses it contains so p t m m m + = .-The mass of the pan with the Teflon bottom ( p m ) was measured as 70.0g.-The mass of the pan with the rubber bottom ( ' p m ) was measured as 80.0g.-To account for the spring scale correction ( c m ) -10.0 was subtracted from each b m calculated. a.) Each table below contains data for the pan with the Teflon bottom for masses of 200g 400g 600g 800g and 1000g. For each separate mass the total mass was calculated from the formula p t m m m + = . Also the average value of b m was calculated and is denoted by b m . m = 200g Trial # 1 2 3 4 5 t m b m b m (grams) 47. 40. 45. 50. 45. 270.0 g 45.4g m = 400g Trial # 1 2 3 4 5 t m b m b m (grams) 115. 105. 115. 100. 100. 470.0 g 107.0g m = 600g Trial # 1 2 3 4 5 t m b m b m (grams) 125. 135. 140. 125. 130. 670.0 g 131.0g m = 800g Trial # 1 2 3 4 5 t m b m b m (grams) 180. 175. 170. 175. 170. 870.0 g 174.0g m = 1000g Trial # 1 2 3 4 5 t m b m b m (grams) 260. 250. 250. 255. 255. 1070.0 g 254.0g b.)
