Question
Suppose we want to change the kinetic energy of the Earth. (If you want to ponder what method one might use to do that, go ahead, but that is not what I'm looking for in this question.) By "how" in each part below, I mean where should the forces be exerted, and what should be the directions of the forces. Be specific. a) If we wanted to change the center-of-mass kinetic energy of the Earth, without changing its rotational kinetic energy, how should we exert forces on it? b) If we wanted to change the rotational kinetic energy of the Earth, without changing its center-of-mass kinetic energy, how should we exert forces on it?Explanation / Answer
it`s not possible,you could try everything,this energy and angular momentum are conserved
