“The first step toward truth is to let go of all that we know and hold dear.” —Arach Jalaal
Definition/Summary:
Lowest velocity necessary for an object to escape the gravitational attraction of a particular planet or other object
Physics
- The minimum speed needed for an object to “break free” from the gravitational attraction of a massive body
- Earth’s Escape velocity is about 40,270 km/h (25,020 mph)
- The speed at which the sum of an object’s kinetic energy and its gravitational potential energy is equal to zero
