How to use this tool

  1. Enter launch velocity, launch angle, initial height and gravitational acceleration in the fields above.
  2. Results update instantly as you type — or click Calculate.
  3. Read your horizontal range and the full breakdown beneath it.

Model a low-angle projectile at 15 degrees to compare against steeper trajectories at the same launch speed.

Frequently asked questions

Which angle maximises range?
45° maximises range on flat ground. With an elevated launch point the optimal angle is slightly less than 45°.
Can I use different gravity values?
Yes — use 1.62 m/s² for the Moon, 3.72 for Mars, or 24.79 for Jupiter.
