Friction Page 1 Lab: Friction William Morris Leo Hayes High School Friction Page 2 Purpose: To investigate the coefficient of friction for a given surface and the effects that factors such as weight‚ surface area and changes to the surface have on the coefficient of friction. Hypothesis: The smaller the amount of normal force (weight)‚ the less friction created and the least surface area and the greaser the surface the less friction is created. With

points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance‚ then plotting heating and cooling curves and analyzing them. Data that you collect will represent the

Physics Domino Lab I. Problem: What spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity

Lab 6 Report Part A 1. Run your model. Compare the queue statistics of the 3 processes with those obtained for Part C in the previous Lab. How have they changed and what conclusions can you draw? (Note the sums of all capacities for both cases are equivalent – 12 in each). The queue time and number statistics for the Air Jordan Logo operators and the Air Max Logo Operators were relatively close. The average queue length for the Air Jordan Logo operators was 0.03769112 in the previous lab
