An online version of this report is available here.

Here’s a pie chart representation of the time distribution.

 

Energy Skate Park

  • About 14.5 hours of work this week.
  • http://www.colorado.edu/physics/phet/dev/ec3/1.05.08/
  • Collaborated with Dubson
  • Added multiple splines
  • Finished computation for leaving the track.
  • Added test selection
  • Added curvature indicators
  • Added offset tracks
  • Projected: 57.5 hours to go (based on last week’s estimate)
  • Issues
    • What about the possibility of putting the center of mass directly on the track?  (Roller coaster, different graphic, etc..?)

 

Repository

  •  “Defragmented” source code that was scattered about
  • Moved simulations so they can be used together

 

Piccolo/Plum Pudding

  • Collaborated with Chris
  • Devise a way to improve performance under certain circumstances in piccolo
  • Needs generalization

 

Upcoming Work

  1. Energy Skate Park

a.       Collaborate with Dubson to improve physical model

b.      Evaluate new physical model before working on any physics-related bugs.

c.       Track should bump up when beneath ground

  1. Collaborate with De Goes to improve simulation build process & isolate dependencies.
  2. Rotational Motion Simulation I

a.       Time series/playback

b.      Lots of minor user interface updates

c.       Performance enhancement

  1. Rotational Motion Simulation II
  2. CCK…
