What happens

In this demonstration, a projectile will be fired 4 times with exactly the same speed. First, the projectile will be fired perpendicular to the horizon. This shows that the distance forward the projectile goes (its range) is zero. It falls right back on the place from which it was fired. Next, the projectile is fired at 45 degrees with the horizontal. Next it is fired at 30 degrees with the horizontal, and finally it is fired at 60 degrees with the horizontal. The first firing gives us the least range, the second gives us the most range, and the last two are identical at between the least and the most range.
