Gravity creates energy....Violation of the first law of thermodynamics? Two Identical metiorites traveling slowly through space happen to be on a vector that will cause them to collide with the earth. One is due to strike the earth one week after the other. The first one comes in close to earth and just as it lines up on it's final approach the moon orbits right into it's path. The metiorite accelerates a little then hits the moon and gives up its kenetic energy in the form of heat, but the mass of the meteorite stays intact and lies on the surface of the moon. A week later the next slow metiorite approaches earth and with no moon in it's way it accelerates and hits the earth. The second metiorite strikes the earth in the middle of the Pacific Ocean and most of the mass is intact. Because of the greater gravitational force of the earth, it hits much harder and much more kenetic energy y was released in the form of heat. Is this a violation of the first law of thermodynamics? Does the gravity of the earth create energy that was not there before?
