Question
A student pushes a box, causing it to slide. But the student does not move. What is true about the net force on the student and the box?Multiple choice question.The student has a net force of zero, but the box has a net force greater than zero.The box has a net force of zero, but the student has a net force greater than zero.
Solution
The correct answer is "The student has a net force of zero, but the box has a net force greater than zero."
Here's why:
-
The student is not moving, which means the net force on the student is zero. This is because of Newton's first law of motion, which states that an object at rest will stay at rest unless acted upon by an external force. Since the student is not moving, there is no net external force acting on them.
-
The box is moving, which means there is a net force acting on it. This is because of Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Since the box is sliding, there is a net force acting on it, causing it to move.
