Animation of a Simple Pendulum using the Euler-Cromer numerical method.
For small angles, equation of motion of a simple pendulum as derived from the Newton's second law is a simple ordinary differential equation which can be solved numerically. One such numerical technique is the Euler-Cromer method. In this code, oscillatory motion of a simple pendulum is animated using MATLAB inbuilt movie function. At the end , the code also calculates and animates the Kinetic Energy, Potential Energy and the Total energy as a function of time along with the motion of pendulum. The units are arbitrary and energies are normalized to 1. Axis are scaled accordingly to give a better view.
