Questions & Step-by-Step Solutions
The escape velocity from the surface of the Earth is approximately: (2019)
Step 1: Understand what escape velocity means. It is the speed needed to break free from a planet's gravitational pull.
Step 2: Know that for Earth, this speed is around 11.2 kilometers per second.
Step 3: Remember that this value is an approximation and can vary slightly based on different factors.
Escape Velocity – The minimum speed needed for an object to break free from the gravitational attraction of a celestial body without further propulsion.
