3. Students at recess played two games of tug-of-war. All students have equal strength. Which answer choice describes a difference in motion that could be seen during the two games?

• More motion could be seen in the first game because forces were unbalanced.
• Less motion could be seen in the first game because forces were balanced.
• Less motion could be seen in the second game because forces were unbalanced.
