Define escape velocity of an object.

Define velocity of an object

The orbital velocity of a satellite in a circular orbit close to the earth is v_0 , If the escape velocity of an object projected from the earth be v_e , then the ratio of these two velocities is.

Define escape velocity. Derive an expression for the escape velocity of an object from the surface of the earth. OR Define escape velocity of a body at rest on the earth's surface. Obtain an expression for the same and show that it is independent of the mass of the body. OR Define escape velocity of the body. Obtain an expression for the escape velocity when the body is at rest on the surface of the earth and show that it is independent of the mass of the body.

The escape velocity of an object projected from the surface of a given planet is independent of

Derive an expression for the escape velocity of an object from the surface of a planet.

The escape velocity of an object from the earth depends upon the mass of the earth ( M ), its mean density (rho) , its radius ( R ) and the gravitational constant ( G ). Thus the formula for escape velocity is

Derive an expression for the escape velocity of an object from the surface of earth. What is its value on the earth's surface ?

What would be the duration of the year if the distance between the eath and the sun gets doubled ? Will this affect the escape velocity of an object on the surface of earth ?
