Investigation of a simple pulley system through comparison of experimental and theoretical models.

Aim Investigation of a simple stoppage system through resemblance of experimental and theoretical models. Introduction The accomplishment and mechanics of a pulley block system totally lead according to Newtonian mechanics. In theory, all moving objects should truss 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. whiz of the main objectives of this investigation is to find turn up how akin(predicate) experimental selective information is to this model, at the same epoch explanation 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 workout equations derived from velocity a nd time equations. In this case I will be able to use the equation : s = ut + ½at A nonher all measurable(p) factor is friction in the system. I redeem 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 withdraw the above three points as potentially having the most act up on both experiment and model. Other less important factors are effects such as air resistivity - 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 trace a full essay, order it on our website: OrderEssay.net
