What is the minimum escape velocity required for an object to break free from the gravitational pull of the Earth from its surface?

A. 11.2 km/s✓ Correct Answer
B. 7.9 km/s
C. 3.0 x 10^8 m/s
D. 2.4 km/s

💡 Solution & Explanation

The escape velocity required for any object to overcome the gravitational pull of the Earth from its surface is approximately eleven point two kilometers per second. Orbital velocity for low Earth orbit is roughly seven point nine kilometers per second, while the speed of light represents an unrelated physical constant. Lower velocity values mentioned in distractors would cause projectiles to fall back to the ground under terrestrial gravity. Escape velocity depends directly on the mass and radius of the planet being exited.
