Question: A person is pushing a heavy box across a floor. If the box does not move, what can be said about the forces acting on it?

Options:

Correct Answer: Net force is zero

Solution:

If the box does not move, the net force acting on it is zero, meaning the applied force equals the frictional force.

A person is pushing a heavy box across a floor. If the box does not move, what can be said about the forces acting on it?

Step 1: Understand that forces are pushes or pulls acting on an object.
Step 2: Recognize that when a person pushes the box, they are applying a force to it.
Step 3: Identify that the box is not moving, which means it is in a state of rest.
Step 4: Realize that for the box to stay at rest, the total or net force acting on it must be zero.
Step 5: Conclude that the force the person is applying to push the box is balanced by the frictional force resisting the motion.
Step 6: Therefore, the applied force (from the person) equals the frictional force (against the box).

Net Force – The net force is the vector sum of all forces acting on an object. If the box does not move, the net force is zero.
Friction – Friction is the force that opposes the motion of an object. In this case, it balances the applied force.
Equilibrium – An object is in equilibrium when the sum of the forces acting on it is zero, resulting in no movement.
