Integration Techniques for Physics Simulations

Simon has made a visual about what he calls “three different ways to make a physics simulation”:

Blue: Modified Euler Integration (aka Backward Euler Integration);

Green: Euler Integration (aka Forward Euler Integration);

Red: Kinematic Equations;

In this situation, the kinematic equations give the same results as Runge-Kutta integration.
