Tautochrone in the damped cycloidal pendulum
Paco H. Talero L, César A. Herreño-Fierro, Fernanda Santana
The tautochrone on a cycloid curve is usually considered without drag force. In this work, we investigate the motion of a damped cycloidal pendulum under presence of a drag force.…
Estimation of solar zenith passage on the Earth's surface by a simple harmonic motion
Paco Talero, Fernanda Santana y César Mora
The kinematics of the Solar zenith passage on the Earth was shown as a simple harmonic motion. This analytical model used the uniform circular motion to describe the Earth's rotati…
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…
Estimation of solar illumination time on the earth by an analytical model: a fertile scenery for to teach physics
Paco Talero, Fernanda Santana, César Mora
We proposed an analytical model for the calculus of illumination time of the Earth for any time of year and any latitude, this model assumes the obliquity of the ecliptic as consta…
