Escape Velocity:
Escape Velocity is the minimum velocity needed to escape the gravitational field of a planet or other
body. It is also called as Critical or Escape Speed.
Escape Velocity:
Escape Velocity:
Planet Mass:
Planet Radius:
where,
G = Universal Gravitational Constant = 6.6726 x 10^{-11}N-m^{2}/kg^{2}
M = Planet Mass
R = Planet Radius
Escape Velocity Examples:
Case 1: What is the escape velocity on earth with respect to Earth's gravity?
Mass of the earth = 5.98x10^{24} kg, R = 6378100 m,
G = 6.6726 x 10^{-11}N-m^{2}/kg^{2}. Step 1: Substitute the values in the below Escape Velocity formula:
This example will guide you to calculate the Escape Velocity manually.
Case 2: Determine the Mars mass, where the escape velocity of mars is 5 x 10^{3}.
Radius of Mars = 33.97 x 10^{5} kg, v_{e} = 5 x 10^{3},
G = 6.6726 x 10^{-11}N-m^{2}/kg^{2}. Step 1: Substitute the values in the below Mass formula:
This example will guide you to calculate the Mass of the Mars manually.
