Aim Investigation of a simple stoppage organisation through resemblance of experimental and theoretical models. Introduction The front and mechanics of a engine block system alone put up according to Newtonian mechanics. In theory, all moving objects should mystify 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. virtuoso of the main objectives of this investigation is to find turn up how alike(p) experimental data is to this model, at the same epoch write up for all variation in the results. A simple pulley Assumptions Before conducting any experiments, or claiming any models, thither ar 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 mathematical function equations derived from velocity and time eq uations. In this case I will be able to use the equation : s = ut + ½at A nonher all cardinal(p) factor is friction in the system. I birth 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 encumbrance 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 imagine the above three points as potentially having the most lapse on both experiment and model. O ther less important factors are effects such! as air resistance - 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 embark on a full essay, order it on our website:
