Question

What is escape velocity

Answer 1

$\huge \mathfrak {HELLO\: THERE\:}$

• Escape Velocity is the Minimum Velocity or speed Needed To Escape the Gravitational Pull of a Massive Body.

• For Example, The Escape Velocity of Earth is 11km/s. Achieve This Speed And You can Escape Earth's Gravitational Influence.

• It is Believed That Black Holes have the Highest Escape Velocity because Even Light, The Fastest Thing in the Universe can't Escape it's Pull.

Answer 2

The minimum velocity which is provided to an object in upward direction to escape it from the gravitational field of any heavenly body, is called as escape velocity.
Escape velocity = Ve = √2GM/R
Where, G = Constant Of Gravitation
( 6.673 × 10^-11 )
M = Mass Of The Heavenly Body
R = Radius Of The Heavenly Body
Escape velocity of the Earth is 11.186 km/s.
