This project simulates a pendulum's motion based on the principle of least action by calculating the Lagrangian mechanics involved in its swing. The simulation includes an animated pendulum swing ...

Abstract: The objective of this article is to study the views of secondary and high school physics-chemistry teachers regarding the use of PhET(Physics Education Technology) simulations in the ...

Geometric optics is a confusing subject for many physics students, who often first encounter the subject in introductory college physics classes. Traditional instruction in geometric optics is not as ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
