Track rocket altitude from clean launch inputs. See peak height, timing, and distance instantly today. Plan safer tests using simple assumptions and exportable summaries.
| Initial Velocity (m/s) | Angle (°) | Initial Height (m) | Time (s) | Gravity (m/s²) |
|---|---|---|---|---|
| 120 | 75 | 2 | 6 | 9.81 |
| 90 | 60 | 1.5 | 4 | 9.81 |
| 150 | 80 | 5 | 8 | 1.62 |
Vertical launch speed: vy = v × sin(θ)
Horizontal launch speed: vx = v × cos(θ)
Altitude at time t: h(t) = h0 + vyt − ½gt²
Peak altitude: hmax = h0 + vy² ÷ 2g
Time to peak: tpeak = vy ÷ g
Total flight time: tflight = (vy + √(vy² + 2gh0)) ÷ g
Ideal range: R = vx × tflight
These formulas assume ideal projectile motion. They ignore air resistance, thrust variation, wind, mass loss, and guidance corrections.
This engineering calculator estimates rocket altitude using classic projectile-motion equations. It helps compare launch settings, inspect peak height, review timing, and understand expected path behavior under ideal conditions.
It is useful for classroom examples, early concept studies, and quick engineering checks. Because it ignores drag and changing thrust, it should not replace detailed flight simulation or certified safety analysis.
It estimates altitude at a chosen time, peak altitude, time to apogee, total flight time, horizontal distance, and ideal range.
No. It uses an ideal projectile model, so drag, wind, thrust changes, and mass loss are not included in the outputs.
The angle is constrained to keep the model stable and preserve both vertical and horizontal motion in the calculations.
Yes. Replace Earth gravity with a local value, such as 1.62 m/s² for the Moon, to see the ideal trajectory change.
A negative altitude at the selected time means the modeled rocket would already be below ground level, so that time is beyond landing.
No. Real launch work needs validated simulation, safety margins, weather review, structural checks, and regulatory compliance.
