Learn advanced concepts easily! You can see the app in action here http://www.youtube.com/watch?v=GK8Tt8MNjf4
This app aims to help students to understand the concepts of system dynamics and modeling. It implements the animated and iterative simulation of some common dynamical systems that the student can play with. In all the simulations, the main parameters of the system can be changed (for example in the mechanical system, the student can change the mass of the object). All the systems are modeled as input-output systems (plants) so they all have a variable as input and a variable as output.

Note: We must remind that this app contains modeling of dynamical systems that uses differential equations for linear and non-linear systems that uses relations as f = b.dx/dt (force due to friction and speed of the mass) that is comprehensible only if one have the basic knowledge of college physics. Other than that the app is a very cool toy for getting to know the physics of the world playing with the animations on the app!
