Rhett Allain continues his series and hones in on the yellow bird:
When I first started playing Angry Birds oh so many years ago, I had this feeling that after tapping the screen the yellow bird just went at a constant velocity. Then one day, I accidentally shot it super high. The bird didn’t just keep going up, it looked like some parabolic motion. … It appears that when you tap the angry yellow bird, two things can happen. First, it increases its speed to 30 m/s (in the same direction that it was going). Second, if its velocity is greater than 20°; below the horizontal the vertical acceleration will be lower than 9.8 m/s2.
