Trajectories

Ballistic trajectories of projectiles with different initial launch angles. Steps of 1° and 3°. No drag, no wind (later). The projectile launched with a launch angle of 45° reaches the farthest, projectiles with a launch angle of 45° - α land at the same point as projectiles with a launch angle of 45° - α. It's all physics. And yes, I know the curves are parabolas.
