Newton-II is a program for solving mechanical equations of motions numerically. The equations can be parameterized for interactive investigations of the motions. The according solutions are displayed immediately in a diagram.
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
