Answer:   Q= Air resistance

Description:

The box release two forces acts on it, when it is falling from the building.

1. Its weight,  2. Air resistance

  • As this point its weight is much greater due to the force of gravity on the objects, so it accelerates downwards.
  • As its speed increases so does the drag on the object so its acceleration starts slow down until it reaches to zero.  At which point air resistance will be equal to weight of the object leaving a resultant force of zero.

The answer is Air resistance
