What is the Projectile Motion Calculator?
Calculate range, max height and flight time of a projectile launched from ground level. These physics and science calculators apply standard SI formulas with exact constants (such as g = 9.80665 m/s² and the 2019 SI definitions) for students, engineers and curious minds.

How to use the Projectile Motion Calculator
- Enter your launch speed, your launch angle, your gravity.
- Results update automatically as you type; you can also press Calculate.
- Read the output: range, max height, flight time.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With launch speed = 25 m/s, launch angle = 45 °, gravity = 9.80665 m/s², the Projectile Motion Calculator returns range: 63.732 m; max height: 15.933 m; flight time: 3.605 s.
Tips for better results
- Convert inputs into SI units first for the cleanest results.
- Idealized formulas ignore friction and air resistance unless stated.
- Use our unit converters to switch between metric and imperial results.
Frequently asked questions
What does the Projectile Motion Calculator do?
Calculate range, max height and flight time of a projectile launched from ground level.
How is it calculated?
The Projectile Motion Calculator uses this method: R = v² sin 2θ ÷ g.
Can you show an example?
With launch speed = 25 m/s, launch angle = 45 °, gravity = 9.80665 m/s², the Projectile Motion Calculator returns range: 63.732 m; max height: 15.933 m; flight time: 3.605 s.
Is the Projectile Motion Calculator accurate?
Yes. It uses standard formulas and exact constants, and the results are verified by our automated test suite. Values are displayed to up to 12 significant digits.
Is this tool free and private?
Yes — the Projectile Motion Calculator is completely free with no sign-up, and it runs entirely in your browser, so the values you enter are never uploaded to our servers.
