A satellite of mass 500 kg is revolving around the earth. At any instant the speed of satellite is 40 m/s . Consider all the cases at same instant(K=1000).

What is the kinetic and potential energy of the satellite

The formula for Kinetic Energy of the satellite = 1/2 m v² = 1/2 * 500 * 40²  Joules
           KE = 400 KJ

The formulas of KE and PE for a satellite give us  that :
      PE of a satellite = - 2 * Kinetic energy = - 800 KJ

The total energy of satellite is = - 400 KJ.

Negative energy means that the satellite is bound with an attractive force (of gravitation).
