In physics, jerk or jolt is the rate at which an object's acceleration changes with respect to time. It is a vector quantity (having both magnitude and direction). Jerk is most commonly denoted by the symbol j and expressed in m/s (SI units) or standard gravities per second (g0/s). See more As a vector, jerk j can be expressed as the first time derivative of acceleration, second time derivative of velocity, and third time derivative of position: Where: • a … See more Discontinuities in acceleration do not occur in real-world environments because of deformation, quantum mechanics effects, and other causes. However, a jump-discontinuity in acceleration and, accordingly, unbounded jerk are feasible in an idealized setting, … See more An elastically deformable mass deforms under an applied force (or acceleration); the deformation is a function of its stiffness and the magnitude of the force. If the change in force is … See more Human body position is controlled by balancing the forces of antagonistic muscles. In balancing a given force, such as holding up a … See more For a constant mass m, acceleration a is directly proportional to force F according to Newton's second law of motion: In classical mechanics of rigid bodies, there are no forces … See more Consider a rigid body rotating about a fixed axis in an inertial reference frame. If its angular position as a function of time is θ(t), the angular … See more Roads and tracks are designed to limit the jerk caused by changes in their curvature. On railways, designers use 0.35 m/s as a design goal and 0.5 … See more WebThe most general second-degree polynomial jerk function is j5~a11a2x1a3x˙1a4x¨!x¨1~a51a6x1a7x˙!x˙ 1~a81a9x!x1a10, ~8! for which the goal is to …
