Which example shows unbalanced forces acting on an object?(1 point)
A. Two people are on opposite sides of a large box. Both people pull the box with equal force.
B. Two people are on the same side of a large box. One person pushes the box and the other pulls the box with equal force.
C. Two people are on the same side of a large box. Both people pull the box with equal force.
D. Two people are on opposite sides of a large box. Both people push the box with equal force.
B. Two people are on the same side of a large box. One person pushes the box and the other pulls the box with equal force.
A person tries to push a refrigerator across the kitchen. She applies as much force as possible, but she cannot make the refrigerator move. Which statement BEST describes by the refrigerator does not move?(1 point)
A. The person does not apply enough force to the refrigerator, so the forces are unbalanced.
B. The person applies too much force to the refrigerator, and now the forces on the refrigerator are balanced.
C. The person applies too much force to the refrigerator, and now the forces on the refrigerator are unbalanced.
D. The person does not apply enough force to the refrigerator, so the forces are still balanced.
D. The person does not apply enough force to the refrigerator, so the forces are still balanced.
The correct example that shows unbalanced forces acting on an object is option B. Two people on the same side of a large box, where one person pushes the box and the other pulls the box with equal force.
To determine which example shows unbalanced forces acting on an object, we need to understand what unbalanced forces are. Unbalanced forces occur when the forces acting on an object are not equal in strength and/or opposite in direction. This causes a net force on the object, resulting in a change in its motion.
Let's analyze the given options:
A. Two people are on opposite sides of a large box. Both people pull the box with equal force.
In this case, the forces are equal and opposite since both people are pulling with equal force. This represents balanced forces.
B. Two people are on the same side of a large box. One person pushes the box, and the other pulls the box with equal force.
Here, the forces are equal in strength but acting in different directions. Since they are not opposite, they don't cancel each other out. This represents unbalanced forces.
C. Two people are on the same side of a large box. Both people pull the box with equal force.
Similar to option A, the forces are equal and opposite since both people are pulling with equal force. This represents balanced forces.
D. Two people are on opposite sides of a large box. Both people push the box with equal force.
As in option A, the forces are equal and opposite since both people are pushing with equal force. This represents balanced forces.
Based on the analysis, the example that shows unbalanced forces acting on an object is option B.
