The rst tutorial in this series included a reminder of Newtonian mechanics, and described their relevance to real-time game simulation. It is quite stable since the velocity is implicitly given and consequently it is harder for velocity and position to come out of sync. It uses Verlet integration, a numerical method used to solve Newton’s Simon created a physics engine in Python with Turtle. evuiubdroqhlsrkjkiiekkfxwcubgvbwlyycwcevqvjryv
