Experimental physics Coefficient of static friction. ,us Introduction In this experiment you will be measuring the angle at which an object starts to move down a slope. You will be using this angle to calculate the coefficient of static friction between the surface of your object and the slope. The investigation is designed to give you an understanding of: . Separating forces into components . Frictionalforces - Newton'ssecondlaw Theory The following information may be helpful. Static friction can be modelled with the equation: lfs'maxl = #3 ' IFNI What you will need Assemble this equipment before you start the exercise: 0 A ramp (this may be a plank of wood, a flattened cardboard box or even a very largetextbook) o A protractor o A box that fits on your ramp (e.g., an empty tissue box) o Objects that can be used to evenly distribute mass over the box (could be weights, stones, books) 0 A set of kitchen scales Maintaining the integrity of your work Collaboration You may either do this investigation alone or with up to one other person currently enrolled in the course (i.e., you may not work as a group of three or more). A if you work with someone else, you need to acknowledge your collaborator (include their name and student number in the report and include them in your photo). in this case you must conduct the analysis and answer the questions Individually; even if your data is the same. if you have identical answers that will be considered plagiarism, so while it is OK to collect the data together you need to answer the questions and plot the graphs etc. as individuals. Photographic evidence You must include two (2) photographs in your report: 0 A close-up image of your UNSW photo 1D card with your name and photo clearly visible. - A photograph of yourself with your student card, the equipment and a piece of paper clearly showing the date and your name and student number. if you worked with a partner this photo must include both of you. A You MUST provide these photos in your assessment. Assessments without the photos will not be marked and you will receive a zero.
