Projectile Motion Calculator
Calculate range, height and time of flight of a projectile.
About this tool
Calculates the trajectory of a projectile launched at a given speed and angle — how long it stays in the air, how high it goes, and how far it travels — using standard kinematics with gravity at 9.81 m/s² and no air resistance.
Key Features
- Time of flight, range and max height
- Supports a nonzero launch height
- Standard physics kinematics (no air resistance)
How to Use
- Enter the initial launch velocity.
- Enter the launch angle (0–90°).
- Enter the initial height, if launched above ground level.
- Click Calculate.
Benefits
- Check physics homework on projectile motion
- See how launch angle affects range and height
- Understand basic trajectory physics
Frequently Asked Questions
No — like most introductory physics problems, this assumes idealized motion with no air drag. Real-world projectiles (especially light or fast-moving ones) will have a shorter range than this predicts.
45° gives the maximum range when the launch and landing height are the same. If launching from an elevated height, the optimal angle is actually slightly less than 45°.
