Some guy is trying to tell me that energy does not cause motion, motion is just a brute fact.
Here is a quote from Hodgson:
I think that rather solidly equates motion with energy. Energy is typically described as the ability to do work.
W = Fd or W = (MA)d
In order to achieve distance you need motion.
Further in the equation, KE = .5mv^2 kinetic energy is equated with velocity. If there is no velocity, then there is no motion. And if there is velocity then there is no Kinetic Energy.
Finally, mass is equated with energy. There is a lot of energy just in one's hand but we can't get to it. Well, if we could get to it, we could get a lot of work done, that is to say, we could move mass some distance, again, motion.
Here is a quote from Hodgson:
Classical physics distinguished between the kinetic energy of a body, which can be considered as an actual energy, and which in general terms is the energy which a body is considered to have by reason of its motion.
