Velocities: mean, average and instantaneous in uniform accelerated motion, some pedagogical comments
Paco Talero, Orlando Organista, Luis H. Barbosa
The relation among instantaneous, mean and average velocities in one-dimensional motion with constant acceleration is studied. It was shown that the instant velocity evaluated in t…
Semi-quantitative diagram about temporal evolution in basic physics learning: a study with engineering students
Paco Talero, César Mora, Orlando Organista +1
We show a new semi-quantitative technique of analysis about of temporal evolution of learning of basic physics concepts. In this technique we arrange a geometric diagram with the s…
Application of FCI at engineering students in Bogota: an interpretation of the answers through a random model of two levels
Paco Talero, Orlando Organista, Luis Barbosa
We applied the FCI to 646 engineering students from Bogota when they began your first year physics, we found that the relative frequency of the number of correct answers has a rand…
Virtual experiments about a walker fly: beyond the Neumann`s solution
Paco Talero
We extend the traditional problem of calculating the traveled distance of a fly that is moving with constant speed on a straight path between two trains that are approaching one an…
