The diagram shows two girls pushing on a box with equal and opposite forces.
Which statement best describes the forces required to move the box to the right?
A.
The forces must be balanced, with the force from the left greater than the force from the right.
B.
The forces must be balanced, with the force from the right greater than the force from the left.
C.
The forces must be unbalanced, with the force from the left greater than the force from the right.
D.
The forces must be unbalanced, with the force from the right greater than the force from the left.
D. The forces must be unbalanced, with the force from the right greater than the force from the left.
To move right, push from the left. C C C C

To determine the forces required to move the box to the right, we need to understand the concept of balanced and unbalanced forces.
In this scenario, the two girls are pushing on the box with equal and opposite forces. When two equal but opposite forces act on an object, they cancel each other out, resulting in a balanced force. Balanced forces do not cause motion, as they counteract each other.
If the box is to be moved to the right, an external force is needed to overcome the balanced forces and create an unbalanced force. An unbalanced force is a force that is not canceled out and causes an object to accelerate or change its motion.
So, the correct answer is C. The forces must be unbalanced, with the force from the left greater than the force from the right, to move the box to the right.
