| Universal Gravitational Constant(G) = 6.6726 x 10-11N-m2/kg2 | |
| Planet Mass(M) = | kg |
| Planet Radius(R) = | m |
| Escape Velocity(ve) = | m/s |
In physics, escape velocity is the speed needed to "break free" from the gravitational attraction of a massive body.
Escape Velocity: Ve2=2GM / R
where, G is Universal Gravitational Constant = 6.6726 x 10-11N-m2/kg2, R is Planet Radius, M is Planet Mass.
For example, when Planet Mass(M) = 5000000000000000000kg, Planet Radius(R) = 6000m, then Escape Velocity = 333.48 m/s.
