demo of newton's second law f = ma the demo is a lil choppy and buggy and probably not accurate but i tried my best do not increase any of the blocks' velocity too much or make them stuck inside each other _/\_ _/\_ _/\_ (this is praying emoji trust) i tried my best to implement normal force and collision but i think i did not do it well (you can see for your self when you make a block 1kg and another 100kg) to reset the blcoks just make them hit the edge and wait 0.5 sec
