The box moves to the left to its resisting change in motion AKA inertia.
What is law of inertia?
The law of inertia of Newton's first law of motion states that an object at rest o uniform motion in a straight line will continue in that path unless it is acted upon by an external force and will move in the direction of the applied force.
