Escape Velocity. The formula to find the gravitational force is: Escape speed, also known as escape velocity, is the minimum speed an object must reach to break free from the gravitational pull of a celestial body (or typically in local context,.
It refers to the minimum speed needed for an object to break free from the gravitational field of a. \ (\begin {array} {l}f\propto \frac { (m_ {1}m_ {2})} {r^ {2}}\end {array} \) f is the gravitational force between two bodies.
