Pendulum Studio

Simulate the motion of eight different pendulum systems in real time on your phone. Included systems:1) Mathematical pendulum (2D): the simplest pendulum.2) Spherical pendulum (3D): a three-dimensional generalization of the mathematical pendulum.3) Spring pendulum (2D): a mass connected to a spring.4) Spring pendulum (3D): a mass connected to a spring in 3D.5) Double pendulum (2D): the simplest example of a system which exhibits chaotic motion and is highly sensitive to the initial conditions.6) Double spherical pendulum (3D): a three-dimensional generalization of the double pendulum.7) Spring mathematical pendulum (2D): a rod attached to a spring.8) Spring spherical pendulum (3D): a rod attached to a spring in 3D.Features:- All simulations are performed in real time by numerically solving the Lagrange equations of motion.- Use the accelerometer of your device for dynamical determination of the gravity force.- Take into the account the friction force to see the damping of the pendulum motion (recommended when using sensor gravity).- Use your fingers to interactively change the positions of the pendulums.- Use pinch to zoom gesture.- All of the parameters for each system can be modified in the preferences.Acknowledgements: OpenGL tutorials at http://www.learnopengles.com/
