Step

Step is an interactive physics simulator. You put objects in a scene and add forces or connections. When you start the simulation, the program calculates how the objects move. You can change settings and see instantly what that does to the gradient.

For example, you work with mass dynamometers, feathers, gravity and collisions. Measuring instruments, graphs and tracks help to not only look at the movement, but also compare values. With this you can investigate a question: what happens if you double the mass, change the spring or change the initial speed?

A simulation is a model with assumptions. The result depends on the selected parameters, units and numerical calculation. Step is therefore especially useful for exploring concepts and comparing predictions. It does not replace any real measurement or certified technical calculation. Save different scenes so you can easily compare changes.
