In what sense? I understand "motion" as something that happens to a rock. If the rock is moving from point A to point B then it is in motion. If the rock is just sitting still, then it is not in motion. How can a rock be motion? It's like saying Motor Daddy is but sneezing, in the sense that Motor Daddy is the same as the process of sneezing. Step me through the processes that lead to the rock's mass eventually being converted to energy. Only in so far as I'm proposing that Motor Daddy will remain the process of sneezing forever.
