What is the tota, energy of a satellite revolving around Earth ?

Explanation

The satellite revolving around the Earth has two types of erergies.
(i) Gravitational potential energy `U` due to position of the satellite in the orbit.
where, `U = - GMm//r`
(ii) Kinetic energy `K` due to orbital speed of satellite.
Where, `K = (1)/(2) m upsilon^(2) = (1)/(2) m ((GM)/(r )) = GM (m)/(2r)`
Total energy `= U = K = (-GM m)/(r ) + (GM m)/(2r)`
`= (-GMm)/(2r)`
