    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

!! before entering the canvas with the cursor, #fullscreen! It simulates quadratic gravity, not the Newtonian one! only 119 bytes, my own gravity system, inspired from u/metamero 's projects! There is no infinite velocity bug so the rectangle will not disappear so fast. If you have entered the canvas and you didn't fullscreen, reset the project by adding inoffensive changes to the script, then fullscreen. #interactive #physics #gravity
