If two objects with different masses are pushing each other, which exerts the greater force?
Responses
It is impossible to tell which object exerts the greater force unless we know which object accelerates.
They both exert the same amount of force on each other regardless of their mass, but in opposite directions.
The object with the smaller mass exerts the greater force on the larger object because it requires more force to make the larger object move.
The object with the greater mass exerts the greater force on the smaller object because the larger object has more inertia.
The correct response is: It is impossible to tell which object exerts the greater force unless we know which object accelerates.

A child pushes a desk with a force of 15 N to the right. The desk accelerates to the right. Which of the following statements correctly represents Newton’s third law and the interaction between the child and desk?
Responses
The desk exerted slightly less than 15 N of force on the child, but the force is directed to the left.
The desk exerted slightly less than 15 N of force on the child, but the force is directed to the left.
The desk exerted slightly more than 15 N of force on the child, but the force is directed to the left.
The desk exerted slightly more than 15 N of force on the child, but the force is directed to the left.
The desk exerted exactly 15 N of force on the child, but the force is directed to the left.
The desk exerted exactly 15 N of force on the child, but the force is directed to the left.
The desk did not exert any force on the child.
The correct response is: The desk exerted exactly 15 N of force on the child, but the force is directed to the left.
The correct response is: They both exert the same amount of force on each other regardless of their mass, but in opposite directions.
When two objects push against each other, the force they exert on each other is always equal in magnitude but opposite in direction. This is stated by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Therefore, it doesn't matter what the masses of the objects are; the force they exert on each other will always be the same.
The correct response is: It is impossible to tell which object exerts the greater force unless we know which object accelerates.
To determine which object exerts a greater force, we need to consider Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When two objects push against each other, they both exert a force on each other, and these forces are equal in magnitude but opposite in direction.
However, to determine which object exerts a greater force, we need to consider their acceleration. According to Newton's second law of motion, the force exerted on an object is proportional to its mass and acceleration (F = m * a). So, if we know the acceleration of both objects, we can determine which one is exerting a greater force. Without knowing the acceleration, it is impossible to conclude which object exerts the greater force.
