What Is This Tool?
This converter transforms speed measurements from foot/second, a common unit in engineering and physics, to the first cosmic velocity, which represents the minimum speed required to maintain a stable circular orbit around a celestial body.
How to Use This Tool?
- Enter the speed value in foot/second (ft/s).
- Select foot/second as the input unit and Cosmic velocity - first as the output unit.
- Click the convert button to get the equivalent speed in first cosmic velocity.
- Use the converted value to relate terrestrial speeds to orbital velocity thresholds.
Key Features
- Converts speed from foot/second to the first cosmic velocity.
- Useful for aerospace engineering and space mission planning.
- Browser-based and easy to use for quick calculations.
- Supports applications in astrodynamics and orbital mechanics.
- Provides direct conversion using an exact conversion factor.
Examples
- 10 ft/s converts to 0.000385823 Cosmic velocity - first.
- 100 ft/s converts to 0.00385823 Cosmic velocity - first.
Common Use Cases
- Specifying projectile or muzzle velocities in ballistics and firearms in ft/s then relating to orbital speeds.
- Designing spacecraft launch profiles to reach stable circular orbits.
- Estimating orbital velocities for Earth, Moon, and other celestial bodies during mission planning.
Tips & Best Practices
- Ensure correct unit selection before conversion.
- Remember that first cosmic velocity depends on the celestial body’s characteristics.
- Use converted values as approximate references due to idealized assumptions.
- Be mindful of the significant difference in scale between feet per second and cosmic velocity units.
Limitations
- Conversion uses a general scale without specifying a particular celestial body.
- Values are very small due to scale differences between the units.
- Assumes ideal circular orbits without atmospheric or other disruptions.
- First cosmic velocity varies depending on the mass and radius of the celestial body considered.
Frequently Asked Questions
- What does one foot/second represent?
- One foot/second is a speed unit representing one foot traveled in one second, exactly 0.3048 meters per second.
- What is the first cosmic velocity?
- It is the minimum tangential speed an object needs to orbit a celestial body in a stable circular path, commonly evaluated at the body's surface.
- Why is this conversion important?
- It connects everyday speed units with critical speeds needed for spacecraft to maintain orbits, useful in aerospace and orbital mechanics.
Key Terminology
- Foot/second [ft/s]
- A speed unit defined as one foot traveled in one second, part of US customary and Imperial systems.
- Cosmic velocity - first
- The minimal tangential velocity required to maintain a stable circular orbit at a specific distance from a celestial body's center.
- Orbital mechanics
- The field studying motions and trajectories of objects in space under gravitational forces.
