+Two blue plastic spheres fall vertically toward an asymmetric seesaw. One sphere impacts the short arm, while the other simultaneously strikes the long arm. Gravitational forces on equal masses generate torque; due to disparities in lever arm lengths, imbalance occurs, forcing the long side to rotate downward about the central axis. Thus, the short arm rises during constrained rotation. Nearby, a pale green swirled balloon ascends as net buoyant force exceeds gravitational force. It maintains an ascending trajectory until colliding with the upper surface. Mechanical energy transforms through falling motion and rotational work, with the entire process abiding by the law of conservation of mechanical energy.

+Two orange plastic spheres descend vertically; one impacts the short arm of an asymmetric lever, while the other simultaneously strikes the long arm. Owing to the greater length of the moment arm on the long side, the torque generated by gravitational force is larger, causing downward rotation of the arm. Consequently, the short arm ascends during constrained rotational motion. Concurrently, a salmon-colored balloon, already suspended in the air, continues its ascent as the net upward buoyant force exceeds gravitational force, persisting until contact with the ceiling.

+Two orange plastic spheres descend vertically, simultaneously striking both arms of an asymmetric lever. The apparatus consists of a red wooden board balanced on a golden fulcrum. Since one side is positioned farther from the fulcrum, the torque generated by the gravitational force of the impacting mass is greater. Consequently, this arm rotates downward, while the opposing end rotates upward under constraint. Simultaneously, a reflective balloon suspended in the air continues to ascend, as the net upward buoyant force exceeds gravitational force. The balloon maintains its trajectory until contacting the ceiling.

+Two yellow spheres fall vertically, striking both ends of an asymmetric lever. Although gravitational force acts equally on both spheres, the longer moment arm on one side produces a greater torque, forcing that arm to rotate downward while the short end elevates. Concurrently, a pink balloon suspended in the air ascends steadily, driven by buoyancy overcoming gravitational force. The balloon continues to ascend through available space until upward motion ceases.

+Two green plastic plates descend vertically toward an asymmetric lever. One plate impacts the short arm, while the other simultaneously impacts the long arm. Owing to the longer lever arm on the long side, the gravitational torque is greater, causing the gray plate to rotate downward about the axis toward that side. Consequently, the short arm ascends during constrained rotation. Concurrently, a green balloon already suspended in the air continues to ascend under the influence of an upward net buoyant force exceeding its weight, until it contacts the ceiling. During the collision, kinetic energy is transferred from the plates to the lever.

+Two orange plastic balls descend vertically onto the short arm of an asymmetric lever, while another orange ball impacts the long arm simultaneously.

Simultaneously, a green balloon suspended in the air undergoes continuous ascent driven by a net upward buoyant force exceeding its gravitational force, resulting in sustained motion until contact with the ceiling.

+Two orange plastic spheres descend vertically, striking both extremities of an asymmetric beam simultaneously.

Each mass is subject to identical gravitational force, yet lever geometry dictates the direction of angular acceleration. Simultaneously, a worn gray balloon continues to ascend. Net upward buoyant force exceeds gravitational force, propelling it toward the upper boundary. The balloon maintains a vertical trajectory until reaching the spatial limit. Mechanical imbalance induces beam rotation, and the balloon occupies the upper space.

+Two black plastic objects undergo vertical descent. One impacts the lever's short arm, while the other strikes the long arm. During descent, potential energy converts to kinetic energy; both bodies accelerate identically under gravity. Rotational motion is governed by the lever principle due to differential arm lengths. The long arm descends under greater torque, elevating the opposing side. Concurrently, a suspended cyan balloon continues to ascend. The net upward buoyant force exceeds gravitational force, propelling it upward until contact. This system demonstrates the gravitational acceleration of objects and the buoyancy dynamics of inflated containers.
