Velocity, acceleration, jerk, snap, crackle, pop, stop, drop, roll...

Summary:

does motion have any beginning, or is it just infinitely derived at a lower level?
Edit: I see this was discussed in the related thread sorry for a repost.
If acceleration causes a change in velocity, and jerk causes a change in acceleration, snap causes a change in jerk, crackle causes a change in snap, pop causes a change in crackle, stop causes a change in pop, drop causes a change in stop, roll causes a change in drop... and there are infinitely more layers?
Then if every change is causes by a lower level change, is there ever a beginning to any motion? What is actually happening when things begin moving? Sorry for the dumb question.

If acceleration causes a change in velocity....
Acceleration is the change in velocity, not a cause of it that happens before.

Most of physics is captured by first and second order differential equations. For instance, the second derivative of position is acceleration which typically depends on position, velocity and mass.
