Aim Investigation of a simple halt system through likeness of data-based and theoretical models. Introduction The ca exercise and mechanics of a pulley block system all carry on according to Newtonian mechanics. In theory, all moving objects should hold fast to Newtons laws of motion - and so from equations derived from these laws, we rear 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 call up turn up how confusable experimental data is to this model, at the same epoch method of accounting for all variation in the results. A simple pulley Assumptions Before conducting any experiments, or claiming any models, on that point atomic number 18 assumptions that need to be make about both methods. To greatly simplify results from experimental data, I go out assume there is a regular quickening on the system. This means I am equal to purpose equations derived from velocity and time equations. In this case I will be able to use the equation : s = ut + ½at Another all important(p) factor is grinding in the system. I stand not factored in an grammatical construction for friction in the model, and I have tried to inform its effect on experimental data by ensuring I have a smooth, neat pulley.
I have taken the cant over of the string, as wellspring as other components attached to it as negligible comp ared to the boilersuit weight down of the system, and I have mistaken the string is inextensible. I would consider the above three points as potentially having the most continue on both experiment and model. different less important factors are effects such as air resistivity - which should be negligible, and considering the weights as moving particles (with luck but no size). How do all these factors affect the two sets of results ? Firstly, If you want to get a full essay, order it on our website:
