In which situation are unbalanced forces acting on an object?
1. Two people stand on opposite sides of a large tire. Both people pull the tire with equal force.
2. 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.
3. Two people stand on opposite sides of a large tire. Both people push the tire with equal force.
4. Two people stand on the same side of a large tire. Both people pull the tire will equal force.
The situation where unbalanced forces are acting on an object is option 2. 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.
The correct answer is option 2: 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. In this situation, the forces being applied to the tire are in opposite directions and do not cancel each other out. As a result, the forces are unbalanced.
The situation in which unbalanced forces are acting on an object is option 2: 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.
To understand why this is the case, let's first define what balanced and unbalanced forces mean.
Balanced forces occur when the forces acting on an object are equal in magnitude and opposite in direction, resulting in no change in the object's motion. In this case, the net force is zero, meaning the forces cancel each other out.
On the other hand, unbalanced forces occur when the forces acting on an object are unequal in magnitude or not opposite in direction. This results in a net force that is not zero, causing a change in the object's motion.
Now, let's analyze each option in the context of balanced and unbalanced forces:
1. Two people pull the tire with equal force: In this case, the forces exerted by the two people are equal and opposite. Therefore, the forces are balanced, and the net force on the tire is zero.
3. Two people push the tire with equal force: Similar to option 1, the forces exerted by the two people are equal and opposite. Thus, the forces are balanced, and the net force is zero.
4. Two people pull the tire with equal force: Here, the forces are equal and opposite, making them balanced. As a result, the net force on the tire is zero.
Now, let's look at option 2: One person pushes the tire, and the other person pulls the tire with equal forces. In this situation, the forces are equal in magnitude but not opposite in direction. The force of pushing and the force of pulling act in the same direction. Consequently, these forces are unbalanced, and the net force on the tire is not zero.
