I was trying to make a pyshics engine for a game, and i ended up with this, a little game. The gray line can help determine the path of the square, press v to send it going. Press space to show the force line (blue line) that determines where the triangle goes Update: Now there is a timer. If it reaches 60, the game ends. also added a few labels to show you what number is what.
Credit to... Nobody. Go on. Play!
