It proposes the establishment of measuring equipment that can record physical parameters focused on the kinematics and dynamics, using the equations deducted from the calculation for the movement, by modifying travel distance, angle of inclination and mass of the objects. The measurement of the time will be used to obtain the uncertainty in the experiments, the dispersion of the available data is related to the size of the sample and the procedure used. In the indirect measurements were used equations due to the correlation in the physical variables for the analysis of uncertainty. One of the methods for uncertainty analysis is based on the statistical analysis, another way to estimate this is through experience or external information available. The experiments made in the inclined plane for the study of the velocity, acceleration and force of friction to angles greater than 15°, showed a relative error of 1.8% in the time variable, the standard uncertainty had a normal distribution with a confidence level of 95%.","PeriodicalId":41375,"journal":{"name":"3c Tecnologia","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2018-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67542318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Esto se debe a la estructura cerrada que presentan y a la poca flexibilidad ante los cambios constantes de la tecnologia. No obstante, ante el crecimiento de este mercado, los problemas referentes al desarrollo de estas aplicaciones se hacen cada vez mas frecuentes, razon por la cual han surgido numerosas metodologias que permiten guiar el ciclo de vida del software y que ademas ayudan a mitigar y resolver los errores existentes respecto a cada etapa de desarrollo. Por tal motivo, se realizo una investigacion exhaustiva para obtener informacion sobre las metodologias y cuales de estas segun diversos autores provee caracteristicas esenciales en el desarrollo Web, por lo que se plantea el objetivo de comparar las metodologias de desarrollo de software Web a traves de la recoleccion de informacion bibliografica, analitica y de campo.

EnglishCurrently, Web applications are monopolizing the market of software products due to the multiple advantages they offer and the dependence on the internet for the development of all types of operations, leaving aside the typical desktop applications. This is due to the closed structure that already have little flexibility in the face of constant changes in technology. However, in view of the growth of this market, the problems related to the development of these applications are becoming more frequent, which is why numerous methodologies have emerged to guide the life cycle of software and also help to mitigate and resolve the existing errors regarding each stage of development. For this reason, an exhaustive investigation was carried out to obtain information on the methodologies and which of these according to diverse authors provides essential characteristics in the Web development, for which the objective is to compare the methodologies of Web software development through the Collection of bibliographic, analytical and field information.
