The noun is probably derived from the verb as it is attested later.

Scruples are like the sand-bags in a balloon. He who throws them all overboard rises with ease, but is likely to come down with a jounce. 1853 January, Edward Wigglesworth, “Art[icle] III.—Reflections.”, in The Christian Examiner and Religious Miscellany, volume XIX, number I (4th Series; volume LIV, number CLXXV, overall), Boston, Mass.: Crosby, Nichols, and Company […], →ISSN, →OCLC, page 47:
[…] I protest that an open wagon is the very best thing to ride in that ever was invented. If it is hard in the springs, so much the merrier! […] Off we started with a jounce over the barn-door sill, that nearly dislocated my neck, and a violent nodding to my cousin's wife that set it all right again, and an alarming scattering of hens and chickens before us. 1852 May, “The Logging Encampment.

The fourth derivative of the position vector with respect to time; the time derivative of jerk.
The fourth derivative (jounce) may be used to find the tangential and normal loci in the same manner as for the second and third order properties. 1974, Arvid Myklebust, “Recommendations and Conclusions”, in Synthesis of Multi-link Mechanisms for Dynamic Specifications: A Dissertation Presented to the Graduate Council of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy (unpublished Ph.D. dissertation), Gainesville, Fla.: University of Florida, →OCLC, page 180:
If x(t) represents the position of an object at time t, then the higher-order derivatives of x have physical interpretations. The second derivative of x is the derivative of x'(t), the velocity, and by definition is the object's acceleration. The third derivative of x is defined to be the jerk, and the fourth derivative is defined to be the jounce.

When you are in an elevator that is not working properly, and your stomach feels as if it were left behind on the previous floor, then you are experiencing jerk. […] No term for the rate of change of jerk, the fourth derivative of position, is in widespread usage, although jounce has been suggested. [2011, Brian E.

Send these nice, white, clean shipping cases of honey to a commission man, without any instruction whatever, and he will have the genius and liberality to slap them upon a dray, jounce them to his store, rub them around and over an old, dirty floor, sell a part of it for less than you expected, fail to pay for it until he sells the other part, which he will do after six months or a year, then he will remit, provided the debt has not yet got so old that it is outlawed or he does not "bust up" in business in the mean time. 1890 June 21 (date written), James Heddon, “From the Hive to the Honey Market”, in The Bee-keepers’ Review, volume III, number 7, Flint, Mich.: W.

Hundreds of angry coal miners pushed toward the locked gate at Shaft 3, shouting and cursing as they neared the mine's Chinese managers, who understood neither the English nor the Tonga words of the mob. As the workers butted up against the fence, the bosses grew more fearful and finally two fired their shotguns. The Zambian miners scrambled in terror. Bodies pivoted, jounced and stumbled. Boston Munakazela did not know he was hit until he suddenly fell over and saw the blood on his chest and arms. 2010 November 20, Barry Bearak, “Zambia uneasily balances Chinese investment and workers’ resentment”, in The New York Times (Africa section), New York, N.Y.: The New York Times Company, →ISSN, →OCLC, archived from the original on 11 Jan 2025:
