Which would be turned back into kinetic energy as the mass moved to the opposite extreme. What is the uncertainty in the mass measurements? The values were subtracted by one another to give a period the results are shown in table 2.1. ( 2 ) x = Xmax cos ( t ) The following are the equations for velocity and acceleration. At the conclusion of the experiment, we discovered that when an object is subjected to a force proportional to its displacement from an equilibrium position, simple harmonic motion results. Since each lab group will turn in an electronic copy of the lab report, Whilst simple harmonic motion is a simplification, it is still a very good approximation. The simple mass-spring system assumes that the spring is massless, or at least it has a mass that is much smaller than the masses added to the spring. Solved Hello,I am needing a little help improving my lab - Chegg It is apparent that there is a clear relationship between an increased mass and the amount of force exerted, and consequently the amount of displacement experienced by the spring.
