In which situation are unbalanced forces acting on an object?(1 point)
A. Two people stand on opposite sides of a large tire. Both people push the tire with equal force.
B. 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.
C. Two people stand on the same side of a large tire. Both people pull the tire with equal force.
D. Two people stand on opposite sides of a large tire. Both people pull the tire with equal force.
I chose B.
Actually, option B describes a situation where balanced forces are acting on the object, because the pushing and pulling forces are equal in magnitude and opposite in direction, resulting in zero net force.
The correct answer is D, where two people standing on opposite sides of a large tire pull it with equal force in opposite directions. The forces are unbalanced because they are not equal in magnitude and opposite in direction, resulting in a net force that causes the tire to move.
I got it wrong-
The correct answer is B. In this situation, two people are exerting unequal forces on the tire because one person is pushing and the other person is pulling. Therefore, there are unbalanced forces acting on the object.
To determine which situation involves unbalanced forces, we need to understand the concept of balanced and unbalanced forces.
When multiple forces act on an object and the net force is zero, the forces are said to be balanced. The object will remain stationary or, if it was already in motion, continue moving at a constant velocity.
On the other hand, if the net force acting on an object is not zero, the forces are considered unbalanced. In this case, the object will experience acceleration in the direction of the net force.
Let's evaluate each situation:
A. Two people stand on opposite sides of a large tire and both push the tire with equal force. In this case, the forces are equal and opposite, resulting in a net force of zero. Therefore, the forces are balanced.
B. Two people stand on the same side of a large tire. One person pushes the tire, and the other person pulls the tire with equal force. While the forces are still equal, they act in the same direction. Therefore, there is a net force acting on the tire, and the forces are unbalanced.
C. Two people stand on the same side of a large tire, and both people pull the tire with equal force. Just like in option B, the forces act in the same direction, resulting in an unbalanced force.
D. Two people stand on opposite sides of a large tire, and both people pull the tire with equal force. Similar to option A, the forces are equal and opposite, leading to a net force of zero. Therefore, the forces are balanced.
Based on this analysis, you are correct. The situation described in option B involves unbalanced forces.
