Energy of an orbiting satellite|Exercises

Choose the correct alternative : (a) If the zero of the potential energy is at infinity, the total energy of an orbiting satellite is negative of its kinetic/potential energy. (b) The energy required to rocket an orbiting satellite out of Earth's gravitational influence is more/less than the energy required to project a sationary object at the same height (as the satellite) out of Earth's influence.

Choose the correct alternatives : If the zero of potential energy is at infinity, the total energy of an orbiting satellite is negative of its kinetic/potential energy.

STATEMENT -1 : The orbital speed of geostationary satellite is nearly 3.1 km/s. STATEMENT -2 : The rotation of geostationary satellite around earth is from west to east. STATEMENT -3 : The total mechanical energy of an orbiting satellite is smaller than its kinetic energy.

In case of an orbiting satellite, if the radius of orbit is decreased
