jolt, jar, jounce, shock (verb)

a sudden jarring impact

"the door closed with a jolt"; "all the jars and jolts were smoothed out by the shock absorbers"

bounce, jounce (verb)

move up and down repeatedly

jounce (Noun)

The fourth derivative of the position vector with respect to time; The time derivative of acceleration.

jounce (Verb)

To jolt; to shake, especially by rough riding or by driving over obstructions.

Jounce

In physics, jounce or snap is the fourth derivative of the position vector with respect to time, with the first, second, and third derivatives being velocity, acceleration, and jerk, respectively; in other words, the jounce is the rate of change of the jerk with respect to time. Jounce is defined by any of the following equivalent expressions: the following equation is used for constant jounce. ⁕ ⁕ ⁕ ⁕ where The notation is not to be confused with the displacement vector commonly denoted similarly. Currently, there are no well-accepted designations for the derivatives of jounce. The fourth, fifth and sixth derivatives of position as a function of time are "sometimes somewhat facetiously" referred to as "Snap", "Crackle", and "Pop" respectively. The dimensions of jounce are distance per. In SI units, this is "metres per quartic second", "metres per second per second per second per second", m/s4, m · s-4.

jounce

In physics, the fourth, fifth and sixth derivatives of position are defined as derivatives of the position vector with respect to time – with the first, second, and third derivatives being velocity, acceleration, and jerk, respectively. Unlike the first three derivatives, the higher-order derivatives are less common, thus their names are not as standardized, though the concept of a minimum snap trajectory has been used in robotics and is implemented in MATLAB.The fourth derivative is often referred to as snap or jounce. The name "snap" for the fourth derivative led to crackle and pop for the fifth and sixth derivatives respectively, inspired by the Rice Krispies mascots Snap, Crackle, and Pop. These terms are occasionally used, though "sometimes somewhat facetiously".
