I have interests in Python programming, physics, chemistry, and 3D simulation. Also I like bird watching! Here are some of photos I've taken: http://ww ...

VPython - Physics and 3D in Python [ID:030]

a series of video-tutorials by Erik Thompson

Interested in 3D programming, physics and Python? Erik Thomspon introduces 3D programming using the VPython toolkit covering a number of subjects including gravity, friction, and tension demonstrating falling balls, weights, wind and satellites.

Video Tutorials

1. VPython: Projectile Motion 1

This is the first video in this tutorial series. It briefly discusses where to find information to install python and the VPython libraries. Then we create a 3D program demonstrating the effect of gravity on a dropped object. These videos are aggregated with the kind permission of Erik Thompson. Full source-code is in the wiki. Would you show your appreciation if you like this video? Just visi [...]

2. VPython: Projectile Motion 2

This episode continues from the last episode in which a ball was dropped to the earth. We modify that 3D program so the ball is thrown horizontally from the top of a building. Full source-code is in the wiki. Uploaded on 18th November 2006, running time 12 minutes.

3. VPython: Projectile Motion 3

This episode continues from the last episode in which a ball was thrown horizontally off a building. In this episode we modify that 3D program so the ball is thrown at an angle from the ground. Full source-code is in the wiki. Uploaded on 18th November 2006, running time 15 minutes.

4. VPython: Projectile Motion 4

This episode continues from the last episode in which a ball was thrown at an angle from the ground. We modify that 3D program so an artificial wind pushes the ball while it is in flight. Full source-code is in the wiki. Uploaded on 18th November 2006, running time 18 minutes.

5. VPython: Friction

This episode continues from the last episode in which wind altered the path of a thrown ball. We modify that program so that a thrown puck slides until friction slows it to a stop. Newton's three laws of motion are also discussed. Uploaded on 18th November 2006, running time 31 minutes.

6. VPython: Force, Motion & Vectors

This is a cleaned up version of the last program and also a review of previous topics. Special emphasis is placed on using vectors and the relationship between force, accleration, velocity, and position vectors. New topics include the norm of a vector and the magnitude of a vector. Uploaded on 18th November 2006, running time 30 minutes.

7. VPython: Tension

In this episode we model an experiment in which a string is tied to an object on a table and to a weight hanging off the edge. The mass of the weight is increased until the book slides. Tension and friction are the key topics. Uploaded on 18th November 2006, running time 30 minutes.

8. VPython: Gravity

In this episode we model satellites orbiting the earth. Topics include the Universal Law Of Gravitation, Uniform Circular Motion, and vector subtraction. Uploaded on 18th November 2006, running time 29 minutes.

9. VPython: Spring Force

In this episode we model the behavior of a spring according to Hooke's Law and take a look at dragging and dropping objects in VPython. Uploaded on 18th November 2006, running time 19 minutes.

Showmedo is a peer-produced video-tutorials and screencasts site for free and open-source software (FOSS)- with the exception of some club videos, the large majority are free to watch and download.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Erik
