Escape Velocity / Speed Tutorial



Escape Velocity / Speed Tutorial
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 10-11N-m2/kg2
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 = 5.98x1024 kg, R = 6378100 m, G = 6.6726 x 10-11N-m2/kg2.
  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 103.
 Radius of Mars = 33.97 x 105 kg, ve = 5 x 103, G = 6.6726 x 10-11N-m2/kg2.
  Step 1: Substitute the values in the below Mass formula:
           
This example will guide you to calculate the Mass of the Mars manually.



This tutorial will help you dynamically to find the Escape Velocity problems.
