Kuinka laskea Escape Velocity
Mikä on Escape Velocity?
Escape velocity is the minimum speed needed for an object to break free from a celestial body's gravitational pull without further propulsion. For Earth: v_e = √(2GM/R) ≈ 11.2 km/s (40,300 km/h).
Vaiheittainen opas
- 1Escape velocity: v_e = √(2 × G × M / R)
- 2G = 6.674 × 10⁻¹¹ N·m²/kg² (gravitational constant)
- 3M = mass of body · R = radius of body (or distance from centre)
