ok, so matter and energy can't be created or destroyed, but the thing gained energy (kinetic) by flinging around the earth's orbit.
Did the earth lose a corresponding amount of energy from somewhere in this process
Also, on a similarly related topic, talk to me about the what's his name uncertainty principle.
Do electrons in atoms in space ever stop moving? What about at absolute zero? If so, can we then "know" exactly where the "frozen" electrons are
If not, then if the electrons are still moving according to the uncertainty principle, even at absolute zero, then where do they get the energy to do this
Sorry for the silly questions, but in my defense, I am an ignoramus.
Yes.
Earth's rotation is now 0.01 second slower.
Does this take up rotational energy in an idealized case? If I'm correct, in case we view the flyby in an inertial reference frame moving with the planet the spacecraft does not aquire any additional kinetic energy because its velocity vector does not change value in respect to the planet, only the direction is changed. Velocity vector only increases value in a heliocentric reference frame as Anomalocaris mentioned above. Assuming that orbital movement of the planet and rotation about its center of mass are independent it's the orbital movement that must change.
