Real-time physics simulation of pendulum system mechanics in both 2D and 3D
Simulate the motion of nine different pendulum systems in real time on your phone. Use the simulation as a live wallpaper (to be set from device's settings). Included systems: 1) Mathematical pendulum (2D): the simplest pendulum. 2) Pendulum wave effect (3D): when multiple pendulums are combined a peculiar wave effect appears. 3) Spherical pendulum (3D): a three-dimensional generalization of the mathematical pendulum. 4) Spring pendulum (2D): a mass connected to a spring. 5) Spring pendulum (3D): a mass connected to a spring in 3D. 6) Double pendulum (2D): the simplest example of a system which exhibits chaotic motion and is highly sensitive to the initial conditions. 7) Double spherical pendulum (3D): a three-dimensional generalization of the double pendulum. 8) Spring mathematical pendulum (2D): a rod attached to a spring. 9) 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.
