yesterday comment added Paul_Pedant The velocity is a result of all the varying accelerations of a particle since the beginning of time. How does the student propose to sum that series?
yesterday comment added Chronocidal Well, colour and taste are also a properties of an object (moving or otherwise — and, really, there is nothing special about a moving object, since from another frame of reference it may not be moving.) So, ask the student if they think kinetic energy should be an explicit function of those…

yesterday comment added Ghoster Does the high schooler understand that in addition to acceleration there are also an infinite number of still-higher time derivatives of position — jerk, etc. — that don’t affect the kinetic energy?

2 days ago comment added Yukterez The acceleration tells you the force while the velocity tells you the energy. Your reply that the effects of the acceleration show itself in the velocity at the next instant was correct. The acceleration changes the velocity and therefore the kinetic energy at each moment, but if you're asking about the kinetic energy at an instant the velocity at that instant counts.
