Question

If the Kinetic energy of
a stallite is 6x109 j what is potential energy and kinetic energy?​

Answer 1

The kinetic energy of a satellite in a circular orbit is half its gravitational energy and is positive instead of negative. When U and K are combined, their total is half the gravitational potential energy.

E = K + Ug

E = −½Ug + Ug

E = ½Ug

E = − Gm1m22r

The gravitational field of a planet or star is like a well. The kinetic energy of a satellite in orbit or a person on the surface sets the limit as to how high they can "climb" out of the well. A satellite in a circular orbit is halfway out (or halfway in, for you pessimists).
