A 0.3 kg rubber ball at 8 m/s hits the edge of a 3 kg metal cube and the cube starts rotating. Please maintain physics realism.๐ค assistant
๐ญ The prompt describes an off-center impact: a light rubber ball strikes the upper edge of a much heavier metal cube. Because the contact point is offset from the cube's centroid, the impulse generates angular momentum โ the cube should rotate. Pure head-on collision would NOT produce rotation, so I must set the sphere's y above the cube's center to force an edge contact.

๐ญ The simulation produced the correct dynamics โ the ball hits the cube's edge off-center and the cube picks up rotation. Now I'll feed the optical-flow video to VACE so it can synthesize a photorealistic version while following the same motion. The prompt should describe the visual materials (red rubber ball, polished metal cube, concrete floor) and the action.
