NewtonII 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

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 RungeKuttaMethod of 4th order can be used. The output of the results are given graphically in a diagram and as a table for further usage.
