Newton-II

3.5

Program for solving mechanical equations for movements.

The differential equations (DEQs) are programmed to calculate the time dependence of the velocitiy v(t) of a point of mass from the given acceleration a. Then the location s(t) is calculated from v(t).

The acceleration a can be entered directly or with any desired mathematical term (i.e. a = F/m from Newton's law). For solving the DEQs several solution methods up to a very sturdy adaptive Runge-Kutta-Method of 4th order can be used. The output of the results are given graphically in a diagram and as a table for further usage.

**Special qualities of Newton-II**

- Realtime calculation while modifying a parameter (perfect to investigate the connections between the parameter and the movement).
- Compare the calculations with experimental data or predictive functions.
- Ability to solve complex problems using conditioned variables or table functions.
- Extensive printing and export capabilities.
- Self evident program design and very intuitive program handling (i.e. great mouse support in the diagram, input assistances ... ). ? minimal lerning curve
- Direct accessible examples with explanations.
- Eminently suitable for lectures, talks and private studies

Version 3.5:

- It is now possible to display several sizes in one diagram. (To do this, enter the sizes separately in the axis plot field with;)
- You can now display the values of all variables defined in the model in a table that you can define yourself.
- The support for scaling the user interface has been improved. It now includes the tables and, if desired, the diagram display.
- You can now use a template file for new documents and also apply this to old documents (three templates are supplied).
- The model settings have been revised and various options for setting diagram parameters across the board have been added.
- The program settings have been expanded (GUI scaling, tooltip setting, template selection)
- The presentation of comparison functions and comparison values has been improved.
- High resolution monitors (HiDPI or Retina) are now fully supported. -> high resolution of the icons and diagrams.
- The tracking of changes to the model has been improved.
- 3D diagrams have been optimized (including context menus, animation & printing)
- Legends are now displayed in all coordinate systems and also printed.
- The resolution when printing has been improved.
- The start selection window has more options (documents and examples used can be selected)
- The calculations are now running in the background -> feedback on calculation / cancellation possible
- Document information has been reorganized ... from now on PDF files with the same file name (print info texts in a PDF file)
- The sidebar with the modeling can be enlarged (use of projector)
- The coordinate system settings have been revised (palette in the sidebar removed)
- The settings window has been significantly expanded and replaces the palette
- There is now an animated & pausable slow motion display of the calculation results
- There is now the option to only partially plot the graph
- There is now an automatic axis mapping for a new project
- Speed optimization when plotting long calculations
- The change quantities (derivatives) can now be used like normal quantities
- The print version has been revised and is now clearer
- New control buttons and other minor GUI improvements
- Natural constants revised and supplemented (new values according to CODATA 2018)
- Revision of the examples including description (thanks to Maximilian Hofer)
- Revision of the English translation (thanks to Daniel Nieto)
- Various bug fixes
