Question 1

What is a Escape Velocity Calculator?

Accepted Answer

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).

Question 2

How does the Escape Velocity Calculator work?

Accepted Answer

Escape velocity: v_e = √(2 × G × M / R) Then: G = 6.674 × 10⁻¹¹ N·m²/kg² (gravitational constant) Then: M = mass of body · R = radius of body (or distance from centre).

Question 3

Can you give an example of how to use the Escape Velocity Calculator?

Accepted Answer

Example: Input Earth: M=5.97×10²⁴ kg · R=6.37×10⁶ m gives a result of 11.2 km/s escape velocity (About 40,000 km/h).

Question 4
