Newton-II

3.0

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
