Suppose you have an object with zero for the value of all the derivatives of position. InIn order to get the object moving you would need to increase the value of the velocity from zero to some finite value. AA change is velocity is acceleration, so the value of the acceleration would have to increase from zero to some value. YouYou would also need to increase the jerk from zero to some value to have a change in acceleration. Is there an infinite series of higher derivatives of position for this to work? OrOr am I missing something?

Infinite series of derivatives of position when starting from rest

Suppose you have an object with zero for the value of all the derivatives of position. In order to get the object moving you would need to increase the value of the velocity from zero to some finite value. A change is velocity is acceleration, so the value of the acceleration would have to increase from zero to some value. You would also need to increase the jerk from zero to some value to have a change in acceleration. Is there an infinite series of higher derivatives of position for this to work?
