| "description": "The task involves an elastic ball released to undergo free fall.", | |
| "prompt": "Static frontal camera view: A dark elastic ball (mass ≈ 121 g) is suspended high above a wooden plank, which rests on two end supports atop a black perforated optical table. Coefficient of friction ≈ 0.81; coefficient of restitution ≈ 0.58. When released, the ball undergoes free fall, followed by a sequence of successive bounces with diminishing peak heights, before finally coming to rest on either the plank or the table surface.", | |
