GoldPendat 3D print model

People use a shiny metallic stick called a gold pendat. It moves up and down due to its unique weight balance and a steady energy source nearby, demonstrating an oscillating motion with a constant period that depends only on gravity. When moving, it always swings in a straight line, rotating about the pivot point where the string is attached. The length of its movement depends on how long its mass-weighted metal part hangs down from the center of rotation and the acceleration due to the gravitational force acting on it. People study this motion closely to determine a fundamental property of nature - gravity's impact.
