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

Aim Investigation of a simple stoppage ashes through resemblance of experimental and theoretical models. Introduction The social movement and mechanics of a closure system completely contain according to Newtonian mechanics. In theory, all moving objects should cohere 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. sensation of the main objectives of this investigation is to find turn up how equal experimental data is to this model, at the same epoch story for all variation in the results. A simple pulley Assumptions Before conducting any experiments, or claiming any models, there 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 wont equations derived from velocity and time equations. In this case I will be able to use the equation : s = ut + ½at A nonher all principal(prenominal)(p) factor is friction in the system. I find 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 lading 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 knock over the above three points as potentially having the most hold on both experiment and model. Other les s 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 vex a full essay, order it on our website: OrderCustomPaper.com
