Projectile Motion Calculator
Explore projectile motion the easy way. Enter the launch speed and angle to get the range, maximum height and time of flight instantly — ideal for physics students, teachers and anyone curious about how launch angle changes distance.

The chart scales automatically. The dashed line marks the maximum height and the dot marks the landing point.
How to use
- Enter the initial launch speed in metres per second.
- Enter the launch angle in degrees (between 0 and 90).
- Gravity is set to Earth value 9.81 m/s2 — change it to simulate the Moon or Mars.
- All results and the trajectory chart update instantly.
Note: This assumes launch and landing at the same height and ignores air resistance, so real ranges will be slightly shorter.
Tips
- The longest range on level ground comes at a 45-degree launch angle.
- Double the speed and the range roughly quadruples — range grows with speed squared.
- Change gravity to 1.62 to see how the same throw behaves on the Moon.
