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.
