What Is Escape Velocity?
Escape velocity is the minimum speed needed to fully break free from a celestial body's gravity. It is used in rocket launches and space missions.
How is it calculated?
How Is It Calculated?
v = √(2 × G × M ÷ r)
- Enter the body's mass and radius.
Earth's escape velocity is about 11,2 km/s.
Frequently Asked Questions
Why can't anything escape a black hole?
In a black hole the escape velocity exceeds the speed of light, so not even light can escape.
