Additionally, you must often propagate the error from your measurements through your calculations and graphs. . Conclusion: Finally, after all this worh
go back and answer the question you stated in the beginning. Does your data allow you to support or reject your hypothesis, or is the data inconclusive? Also do you have anything you can compare your results with
[e.9. a value in the literature, a second measurement, a measurement with a different method, other lab groups)? How well does it compare to such a value? (Cite references per the APA Format Guidelinesl Lab 3: Atwood
Machine mm/dd/20L1. Newton's Second Law: the Atwood Machine Lab Report 3 General Physics I (or, II) Parker University Dr. Tison Month xx,20l1 Introduction: The purpose of
this lab is to test Newton's 2nd Law of Motion by utilizing an Atwood machine apparatus. The Atwood machine will be used to study the relationship between mass, acceleration and net forces, with the distribution of the mass between the two
weights being the independent variable and the time the dependent variable within the experiments. Hypothesis: It is hypothesized that the acceleration of the object observed will be directly proportional to the net force acting on the object and inversely proportional to
the total mass of the object. Theory: In an Atwood's machine apparatus two sets of unequal masses are suspended from a string on either side of a pulley. The larger mass, mz, provides a net force, Fnet = (mz-mr)g
thereby causing both masses to accelerate according to Newton's 2nd Law of Motion, Fnet = [mr+m2)a. Combining these 2 equations, the acceleration can be calculated by the equation, 2. = [[mz-mr)/ (mr+mzJ]g. It is also possible to determine the
acceleration of the 2 masses by measuring the time it takes for the masses to descend a distance y to the floor, using the equation, ?6= 2y /t2 Acceleration will be determined from the time measurement data and will be
compared with the value calculated from the known masses. Differences between these two values of acceleration will be expressed as aYo uncertainty.
