Projectile Motion at 15° — Low Trajectory
A shallow 15° launch angle produces a low, fast trajectory with reduced range compared to 45°.
How to use this tool
- Enter launch velocity, launch angle, initial height and gravitational acceleration in the fields above.
- Results update instantly as you type — or click Calculate.
- 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.
