Ideal Projectile Motion Calculator

How to use Ideal Projectile Motion Calculator

Resolve launch speed into horizontal/upward components. A stable ground-intersection root determines flight time; horizontal motion gives range, and positive upward velocity adds vy²/(2g) to peak height. A downward launch at ground level has zero flight time.

1. Enter launch speed (m/s), angle above horizontal (degrees), initial height above ground (m), user gravity (m/s²).
2. Choose the stated convention and check the units and supported model.
3. Calculate, inspect the result, then copy or download it.

Good to know

• Nonnegative m/s launch speed/initial meters, angle−90° to90°, positive user gravity m/s². Ideal point mass with no drag, wind, aiming or real-flight guarantee. Samples are model points, not measurements.
• Runs locally. Text/JSON fields are capped at30,000 characters; stricter page-specific and numeric-string limits also apply. Numeric inputs are bounded to magnitude1e15 and nonzero magnitude at least1e-100 unless an exact-string mode states otherwise. Approximate summaries use12 significant digits; CSV numeric cells retain the complete stored value and potentially formula-like string cells gain a protective apostrophe; unsupported, non-finite or detected underflow states return an error.
