Teaching friction at university level through an experiment with images

چکیده
Abstract The experiment with images described here contributes to the scarce literature about experimental approach classical problem of oblique launching on surface an inclined plane. It is directed at intermediate physics course, aim contextualizing teaching laws friction and empirical modeling in Classical Mechanics. We used a video two-dimensional real motion coin sliding plane, case where net force varies continuously. frames were separated each one was assigned time code by computational process. resulting set analyze dynamical evolution system, recording positions known instants. All laboratory manuals can be accessed http://www.fep.if.usp.br/∼fisfoto/translacao/planoInclinado/index.php . Realizing that resistive interpreted as kinetic force, according Amontons’ laws, it possible build theoretical model able predict trajectory through first order numerical method, then fit its parameters observed trajectory. This proposal reconciles Information Communication Digital Technologies (ICDT). also favors deeper discussion role models hypotheses physical sciences, which could particularly interesting teacher education.

Teaching Data Security at University Degree Level
There is a general consensus that courses on data security at university degree level should be research-oriented and teach fundamentals of the field, i.e., items of long-term knowledge in contrast to technology-oriented system knowledge. Unfortunately, this consensus often results in courses that are either too theoretical or are outdated with respect to current developments in security techno...
