What does “Escape velocity” actually mean in Gravitation, and why does it matter for NEET?
the minimum speed to leave a planet's gravity, v = √(2GM/R) ≈ 11.2 km/s for Earth.
In simple words: the minimum speed to leave a planet's gravity, v = √(2GM/R) ≈ 11.2 km/s for Earth. Getting Escape velocity clear matters because NEET questions on Gravitation usually test this idea directly, not just a formula you memorised.
Key point
Escape velocity
Common mistake
confusing it with orbital velocity.
Memory tip
escape velocity is √2 times the orbital velocity at the surface.
