TL;DR: In this paper, the effects on the human body of different types of acceleration, jerk, snap and higher derivatives, and how they can be used in physics education to further enhance the learning and thus the understanding of classical mechanics concepts.
Abstract: The higher derivatives of motion are rarely discussed in the teaching of classical mechanics of rigid bodies; nevertheless, we experience the effect not only of acceleration, but also of jerk and snap. In this paper we will discuss the third and higher order derivatives of displacement with respect to time, using the trampolines and theme park roller coasters to illustrate this concept. We will also discuss the effects on the human body of different types of acceleration, jerk, snap and higher derivatives, and how they can be used in physics education to further enhance the learning and thus the understanding of classical mechanics concepts.

TL;DR: In this article, an interpolation method for parametric tool paths with confined jounce, jerk, acceleration, and speed is proposed, and it is shown that this profile is time optimal to change the speed from one value to another under the given constraints.
Abstract: Aiming at reducing the computer numerically controlled (CNC) machining vibration and increasing machining quality, an interpolation method for parametric tool paths with confined jounce, jerk, acceleration, and speed is proposed. An acceleration/deceleration profile with confined jounce, jerk, acceleration, and speed is proposed, and it is shown that this profile is time optimal to change the speed from one value to another under the given constraints. For a given parametric tool path, the velocity function is obtained by first computing the critical points of the tool path where the radius of curvature reaches extremal values, then determining the feasible maximal speeds at the critical points, and finally using the jounce confined acceleration/deceleration profile to connect the speeds at the adjacent critical points. A vibration experiment is conducted, which shows that vibration of the CNC machine decreases significantly for motions under confined jounce than that under confined acceleration and jerk. Simulation for two real CNC models are given to show the feasibility of the method.

29 Nov 1978TL;DR: In this article, the suspension strut is fitted with a jounce bumper of a suitable rubber or elastomer having an outwardly oriented knee which yields under low axial compression to provide a low initial spring rate as the suspension initially contacts the bumper.
Abstract: Suspension strut which incorporates a jounce bumper of a suitable rubber or elastomer having an outwardly oriented knee which yields under low axial compression to provide a low initial spring rate as the suspension initially contacts the bumper. As the suspension travel increases, the knee in the bumper wall continues to yield so that the internal shape of the walls of the jounce bumper become active and progressively increases the effective contact area to provide a progressively increasing spring rate and improved jounce control.
