Bernoulli's muddle: a research on students' misconceptions in fluid dynamics
Alvaro Suarez, Mateo Dutra, Martin Monteiro +1
Bernoulli's equation, which relates the pressure of an ideal fluid in motion with its velocity and height under certain conditions, is a central topic in General Physics courses fo…
When the quarter jumps into a cup (and when it does not)
Mateo Dutra, Álvaro Suárez, Martín Monteiro +1
While Bernoulli's equation is one of the most frequently mentioned topics in Physics literature and other means of dissemination, it is also one of the least understood. Oddly enou…
Using mobile-device sensors to teach students error analysis
Martin Monteiro, Cecilia Stari, Cecilia Cabeza +1
Science students must deal with the errors inherent to all physical measurements and be conscious of the need to expressvthem as a best estimate and a range of uncertainty. Errors…
Inconsistencies and errors in traditional approaches to energy in our introductory courses
Alvaro Suarez, Daniel Baccino, Arturo C. Marti +1
We present a critical analysis of the classical approaches to energy subjects, based on the work-energy theorem and the conservation of mechanical energy proposed in the courses of…
A student experiment on error analysis and uncertainties based on mobile--device sensors
Martin Monteiro, Cecilia Stari, Cecilia Cabeza +1
Science students must deal with the errors inherent to all physical measurements and be conscious of the necessity to express their as a best estimate and a range of uncertainty. E…
Magnetic fields produced by electric railways
Martin Monteiro, Giovanni Organtini, Arturo C. Marti
We propose a simple experiment to explore magnetic fields created by electric railways and compare them with a simple model and parameters estimated using easily available informat…
Normal coordinates in a system of coupled oscillators and influence of the masses of the springs
Alvaro Suarez, Daniel Baccino, Martin Monteiro +1
Experimental analysis of the motion in a system of two coupled oscillators with arbitrary initial conditions was performed and the normal coordinates were obtained directly. The sy…
Using smartphones as hydrophones: two experiments in underwater acoustics
Martin Monteiro, Arturo C. Marti
During the last years, it has become increasingly clear that smartphones are valuable tools to be used almost everywhere. Until recently, a place that still resisted smartphone ons…
