Find time of flight, horizontal range, and peak height for launches with optional initial height

Enter Launch Conditions

The model assumes no air resistance and constant gravitational acceleration.

Use 9.81 m/s² for Earth, 1.62 for Moon, 3.71 for Mars, etc.

Assumptions

  • No drag or wind; acceleration is constant.
  • Ground impact occurs when the height returns to zero relative to the launch surface.
  • Angles outside 0–90° are not supported.
