Minimum velocity required for an object to orbit around the Earth is Vs =√gR = 8KmSec⁻¹
Let Ve be the escape velocity required for a body to escape Earth's gravitational field.
Let if 'V' be velocity with which a body is projected from Earth.
Then,
Let Ve be the escape velocity required for a body to escape Earth's gravitational field.
Let if 'V' be velocity with which a body is projected from Earth.
Then,
- V < Vs → body falls to ground
- V=Vs → body rotates round the Earth in circular orbit closer to surface of Earth.
- Vs < V < Ve → body revolves in elliptical orbit
- V=Ve → body just escapes from Gravitational Field
- V>Ve → body moves in interstellar space with velocity equal to √❲V²-Ve²❳
- V<Ve → Total Energy of body is Negative
- V=Ve → Total Energy of body is Zero.
