two people stand on the same side of a large tire. one person pushes the tire and the other pulls the tire with equal force

Explanation:

Unbalanced forces occur when the net force on an object is not zero. When two people are on the same side of a tire, one pushing and one pulling, their forces add up in the same direction (since they are on the same side), creating a non - zero net force. In the other cases (opposite sides with equal push/pull or same side with equal pull), the forces either cancel out (opposite sides) or are in the same direction but with no opposing force to create an imbalance in the sense of a net force change (same - side pull).

Answer:

Two people stand on the same side of a large tire. One person pushes the tire and the other pulls the tire with equal force.
