"description": "The task involves a ball connected with a lightweight rod which can rotate around one of its ends. Then, the ball is lifted and released.",
"prompt": "Static frontal camera view: A heavy metal ball (mass ≈ 318 g) is fixed to the tip of a lightweight rigid rod, which rotates freely about a stationary horizontal axle mounted between two vertical posts atop a black perforated optical table. The rod is initially lifted to a horizontal position, with the ball extending out to one side. Upon release, the ball follows pendulum motion: it accelerates downward past the vertical datum, ascends on the opposite side, and continues oscillating back and forth over numerous cycles, its amplitude slowly and gradually diminishing due to frictional losses.",
