If a hole were somehow drilled right through the centre of the earth, and an object were dropped into this hole, would the object first accelerate until it reached the centre and then begin to decelerate until the pull from the centre captured it again just after it had emerged from the other end of the hole? Would this oscillating cycle then repeat ad-nauseum, and if so does this constitute a kind of perpetual motion?
Re: Would an object dropped through a hole in the earth oscillate forever?
