This MATLAB simulation animates the behavior of a frictionless pendulum. The initial angular acceleration, velocity, and position can all be specified. The lever arm length can also be changed, and the simulation will update accordingly. Consistently throughout the period of the pendulum, the angular acceleration and velocity will be displayed to the user.
By first initializing a time step and a final time, the acceleration, velocity, and position is solved for at each iteration of time. Within a for loop, a visual representation of the pendulum is updated based on each iteration of every vector. The image for every time value is then saved and condensed into an audio video interleave file. This allows for video playback with a frame rate that accurately imitates the real movement of the pendulum.
