- Total energy of a satellite in a circular orbit is negative, indicating it is bound. - For a circular orbit, Total Energy E = -Kinetic Energy Ek. - To escape gravity, the total energy must become zero. - The energy to add is the negative of the initial total energy.
A satellite having circular orbit around the earth has a kinetic energy Ek. What is the minimum amount of energy to be added so that it escapes from the earth ?
