Title: Lesson Package for Energy Change using the Roller Coaster Simulation
Post by: engrg1 on September 12, 2012, 04:16:02 pm
Hi, all.
Have further refined  the roller coaster simulation to be used in primary school. Thanks to the original source code written by Michael R. Gallis and edited by Wolfgang Christian.  Check out the 01 Energy Change  http://iwant2study.org/easyjava/index.php/lesson-package (http://iwant2study.org/easyjava/index.php/lesson-package)Changes made:
(1) Able to adjust initial height

Make some changes after the lesson is carried out.
(1) Custom will be default to previous selection (suggestion by lookang)
(2) Information about Max and Min Height, velocity
(3) Show Graph

Not able to remove the "klinks" in the roller coaster when set in custom mode. This can result in the object not showing the "physics law". Have to highlight to the students and make this a "teachable moment" and how this does not satisfy the Energy law.

Have made further refinement with feedback from the students
(1) Replace Maximum and minimum with Highest Point and Lowest Point
(2) Indicate on the diagram where is the highest and lowest point (Thanks to lookang)
