45° is the optimal launch angle for maximum range on flat ground — this preset demonstrates that fundamental result.
Frequently asked questions
- How does this differ from the projectile motion calculator?
- That tool plots the trajectory chart and supports non-zero launch height. This calculator focuses on exact numerical outputs from the standard range formula.
- What launch angle gives the greatest range?
- 45° on flat ground with no air resistance. Air resistance shifts the optimal angle slightly below 45°.
