Well...we are a company of motion. jerk is the physics term defining the rate of change of acceleration, just as acceleration [a] is the rate of change of velocity [v], (speed), jerk is is the rate of change of acceleration, it’s the third derivative of displacement [r], (distance)…we dream up, design, prototype, and move into production, and sell products that assist you in your pursuit to adventure, to be out in motion, free to move and to be wherever you wish…
