We have also added the function of shading in the area (between the line on the graph, the time axis, and the two time reference lines) that is being calculated. The left arrow was not displaying that has been fixed. The time and time range at which the slope and the area are calculated can be modified by the user by tapping a Left and Right arrow that moves a time reference line. The Basic 6 mode of the simulation offers the ability to calculate the slope and the area for the position-time and the velocity-time graph. We also added a couple of features and fixed another feature in our Kinematic Graphing simulation. The Concept Checker consists of 28 questions organized into seven Question Groups. The Concept Checker coordinates with the second of three usage modes - Two-Stage Motion. We have released a second Concept Checker for our Kinematic Graphing simulation. The Sequel: We cleaned up some wording on some of the questions. Physics Interactives, Free-Body Diagrams. Problem EC4Q2v2 contains the fix.Ĭalculator Pad: Light Waves, Problem Set LW9: Problem 1, Part b had an answer key error. Problem LW9Q1v2 contains the fix. Version 2.2.2 has the update.Ĭalculator Pad: Electric Circuits, Problem Set EC4: Problem 2's problem statement displayed a numerical constant instead of the actual variable and the result is that the answer key was incorrect. Solve It! Inclined Planes: we have clarified that students should use 9.8 m/s/s for the value of g. Solve It! with Vectors: we have clarified that students should use 9.8 m/s/s for the value of g. Rocket Sled Concept Checker: An answer key error was fixed. The maintenance crew was in today and the following changes or fixes have been made.
