Escape Velocity / Speed Calculator

Universal Gravitational Constant(G) = 6.6726 x 10-11N-m2/kg2
I want to calculate
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 formula:

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.
