1. When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. When the forces acting on an object are unbalanced, they do not cancel out one another.
2. a.) Balanced force - those that are opposite in direction and equal in size. b.) Unbalanced force - forces applied to an object in opposite directions that are not equal in size.
3. a.) Balanced force: - An object floating in the water. - A tug-of-war game where neither side is winning. - A running car stays in place because the brakes are applied.
b.) Unbalanced force: - An object sinking in water. - A group of kids winning a tug-of-war game. - A car accelerating, braking, or turning.
