Balanced Forces, Two students arm‑wrestling with equal strength, A picture frame hanging straight on the wall., A car cruising at constant speed on a straight highway, A drone hovering steadily in place., Unbalanced Forces, A soccer ball being kicked and rolling across the field., A seesaw tilting when one side is heavier., A jeepney starting to move when the driver presses the gas., A kite pulled upward by wind..

Force Sorting Wall!
