+The video frames provided (0.0–0.3 s) show only a blurred, low-resolution view of a tiled floor with grid-like patterns and indistinct foreground elements—insufficient to verify or correct object count, type, color, shape, or arrangement. No cylinders, fan, airflow, or motion events are visually discernible in these frames.
+
+Since the visual evidence is ambiguous, reflective, and incomplete, and no human annotation overrides the original, the locked event chain must be preserved *unchanged in structure and content*, with only linguistic polishing applied for scientific clarity and lexical diversity—without altering any physical event, object role, spatial relation, or causal sequence.

+A beige, checkered, matte-finished cylindrical object rests stationary on a wooden floor until struck by a rotating green, smooth, glossy cylindrical body, which imparts horizontal linear momentum. The impacted cylinder then enters a region of directed airflow generated by a fan; aerodynamic drag (wind force) opposes its motion, causing deceleration until its velocity nullifies. Subsequently, sustained wind force accelerates it in the reverse direction. Concurrently, a second identical beige, checkered, matte cylinder—already translating parallel to the airflow direction—experiences wind force aligned with its velocity vector, resulting in forward acceleration within the same airstream. Inertia governs the persistence of each cylinder’s kinematic state until modified by external forces: impact or aerodynamic interaction.

+The red reflective bell remains at rest until it collides with a dark rotating body, which imparts horizontal velocity. Subsequently, the bell enters an airflow generated by a pink reflective object. The aerodynamic force opposes the direction of motion, decelerating the bell to rest; subsequently, under sustained aerodynamic force, it accelerates in the opposite direction. The second red reflective bell moves along the airflow direction, where the aerodynamic force aligns with the velocity vector, resulting in forward acceleration within the airflow.

+The reflective bell acquires horizontal velocity following collision with the golden rotating body. Upon entering the airflow of the gray plastic fan, wind force opposes its motion, decelerating it to zero velocity before accelerating it in the reverse direction. Simultaneously, the second reflective bell moves parallel to the wind direction. In this case, the wind force aligns with its velocity, resulting in forward acceleration within the airflow. Inertia maintains the initial motion between interactions, while variable wind force determines the observed subsequent acceleration vectors along both trajectories.

+A grey, grainy, matte bell rests on the wooden floor until struck by a green, smooth, glossy, rough, mottled-grey cylindrical body rotating about its longitudinal axis; the impact imparts horizontal velocity to the bell. The bell then enters the fan’s airflow, where wind force opposes its motion, producing deceleration until its velocity reaches zero; subsequently, sustained wind force accelerates it backward. A second grey, grainy, matte bell—already in motion parallel to the wind direction—experiences wind force aligned with its velocity, resulting in forward acceleration within the airflow. Inertia preserves each bell’s state of motion until altered by external forces (impact or wind), demonstrating that net force determines whether an object accelerates, decelerates, or maintains constant velocity.

+A smooth, glossy orange sphere rolls across the sandy surface with initial velocity and collides with the edge of a low, rectangular table; the impact transfers linear momentum, inducing rotational motion about the table’s support legs, which leads to tilting and eventual collapse onto the ground. Adjacent to the table, two fan units rest directly on the sand, generating a sustained horizontal airstream parallel to the surface. A second glossy orange sphere moves within this airflow, accelerating continuously under the applied wind force. A third glossy orange sphere approaches from the opposite direction, decelerating due to opposing aerodynamic drag until its velocity reaches zero; subsequently, the net wind force acts in the reverse direction, initiating backward acceleration. A silver, metallic, rough-textured cube remains stationary near the fans, unaffected by the airflow owing to its high mass inertia and stable contact with the ground.
