ESCAPE VELOCITY

1. The minimum velocity of the body that should be given to the body to enable it to escape away from the earth's gravitational field is called escape velocity.

2. When the energy of a satellite is zero, then it escapes away from its orbit and its path becomes parabolical.

3. The value of escape velocity of a body does not depend on its mass.

4. The escape velocity of a body depends on the radius of planet from which it is projected.

5. Value of escape velocity does not depend on the angle and direction of projection.
