- Escape velocity: The minimum velocity required to escape the gravitational field of the earth is called escape velocity.
- It is denoted by Ve.
- The escape velocity on earth is given by:
\({V_e} = \sqrt {\frac{{2\;G\;M}}{R}} \)
Where M = mass of earth and R = radius of the earth
- If a body of mass m placed on a surface inside a satellite moving around the earth. Then force on the body is
Explanation:
- The lowest velocity which is required to escape the gravitational pull of the earth is called its escape velocity and it is 11.2 Km/s for Earth.
- Different planets have different escape velocity depending on their mass and radius as shown above
Additional Information
- The escape velocity of Moon is 2.38 km/s
- Among all the planet Jupiter has the highest escape velocity of 59.5 km/s.
