Aim Investigation of a simple stoppage arrangement through resemblance of experimental and theoretical models. Introduction The query and mechanics of a pulley block system solely deport according to Newtonian mechanics. In theory, all moving objects should constipate to Newtons laws of motion - and so from equations derived from these laws, we nookie give out a mathematical model which allows us to call the motion of the object. maven of the main objectives of this investigation is to find turn up how comparable experimental info is to this model, at the same epoch news report for all variation in the results. A simple pulley Assumptions Before conducting any experiments, or claiming any models, on that point argon assumptions that need to be made about both methods. To greatly simplify results from experimental data, I will assume there is a regular acceleration on the system. This means I am equal to apply equations derived from velocity and time equ ations. In this case I will be able to use the equation : s = ut + ½at A nonher all primary(prenominal)(p) factor is friction in the system. I mother not factored in an expression for friction in the model, and I have tried to minimise its effect on experimental data by ensuring I have a smooth, clean pulley.
I have taken the pack of the string, as wellspring as other components attached to it as negligible compared to the boilersuit weight of the system, and I have assumed the string is inextensible. I would make do the above three points as potentially having the most go along on both experiment and m odel. Other less important factors are effec! ts such as air impedance - which should be negligible, and considering the weights as moving particles (with mass but no size). How do all these factors affect the two sets of results ? Firstly, If you want to circumvent a full essay, order it on our website:
